Equipment Productivity Forecasting Model for Multi-storey Building Construction Through Regression Analysis

Equipment Productivity Forecasting Model for Multi-storey Building Construction Through Regression Analysis

Abstract: Construction productivity measurement is the analysis into the ratio of total output to the total input of the construction process. Inputs generally refer to labor, equipment and materials cost and output in terms of total value of the project. The aim of this study is to identify critical factors that affects equipment productivity and to develop a mathematical model for equipment productivity forecasting of building construction and to do the validation of the model. Identification of factors is done by conducting literature survey and interview session with the site engineers,project engineers and contractors and are evaluated using relative importance index method. Based on the identified factors equipment productivity forecasting model is developed using Multivariate Linear Regression Technique(MLR).The model was developed using 50 sets of data collected from multi-storied residential projects in Trivandrum. It is found that MLR have the ability to forecast the productivity with good degree of accuracy of the coefficient of correlation(R) 73% for Equipment productivity model.

Evaluating Excavation Equipment Productivity Constant for Construction Project

Evaluating Excavation Equipment Productivity Constant for Construction Project

ABSTRACT: A considerable body of literature has been dedicated to research studies on construction equipment. Many topics were discussed and analyzed and various conclusions have been reported .Construction projects suffer various problems and complex factors such as cost, duration, quality and safety. Construction sector is diverse as it contains contractors, consultants, designers, owners, and others. The aim of this Project is to achieve equipment productivity at a construction project. Many studies have been conducted before but still there is deeper need of understanding the improvement of productivity. The main outcome from the literature is that there is no standard definition of productivity. So to achieve the productivity the maintenance should be given to that of equipment and this maintenance should be are of different types according to the working condition, budget, cost etc. factors. This study includes different factors which affects the productivity of the equipment. The factors which affect the performance of equipment include job, maintenance, working days, fuels/energy, expenses on repair/maintenance From the given study we have find out different factors which affects the selection of equipment and maintenance of equipment for giving the better output i.e., nothing but improving productivity. The project includes the specifications of the excavation equipment and the working capacity. The daily working hours of equipment on site and the cost estimation of particular equipment used.To achieve these objectives a methodology is adopted towards improving productivity are; Understanding the need of productivity improvement, General types of productivity, Identification of critical success factors and their effective implementation in Maintaining productivity.

A Comparative Study of Actual Productivity and Theoretical Productivity of Construction Equipment and its Remedial Measures.

A Comparative Study of Actual Productivity and Theoretical Productivity of Construction Equipment and its Remedial Measures.

The study of equipment productivity and productivity is as old as equipment itself. Construction equipment plays an important role in the execution of high cost time bound construction projects. This equipment produces output at the accelerated speed and enables the completion of task in a limited time. Equipment saves manpower, a source, which is becoming insufficient as per the demand, costly and becoming more demanding day-by-day. Equipment improves productivity, quality and safety. Planning in the construction industries, as is well known plays an important part in the successful outcome of a project. The study outlines the two equipment [Excavator and Drum Mix Plant]. This study concentrates on the type and schedule of presence of the equipment at the project site, since we know that the actual hourly production of the equipment differs from the planned hourly production. Moreover, this study also introduces the factors affecting construction equipment productivity.

Productivity Analysis to Increase Overall Equipment Effectiveness (OEE) by Implementing Total Productive Maintenance

Productivity Analysis to Increase Overall Equipment Effectiveness (OEE) by Implementing Total Productive Maintenance

Overall Equipment Effectiveness (OEE) is a comprehensive measure that indicates the level of machine / equipment productivity and its performance in theory. This measurement is very important to find out which areas need to be increased in productivity or the efficiency of the machine / equipment and also can show the bottleneck area found on the production line. OEE is also a measuring tool for evaluating and providing appropriate ways to ensure increased productivity in the use of machinery / equipment.

5S Transfusion to Overall Equipment Effectiveness (OEE) for Enhancing Manufacturing Productivity

5S Transfusion to Overall Equipment Effectiveness (OEE) for Enhancing Manufacturing Productivity

The concept of OEE, introduced by Nakajima [21], is being used increasingly in most of the industries. Companies have diverse traditions of deciding their performance in order to reach and maintain a competitive edge in the market. Overall equipment effectiveness (OEE) is the consistent measure tool for evaluation the performance. It develops in industry to measure the efficiency losses that result from rework and yield losses. OEE monitors the actual performance of equipment relative to its performance capabilities under optimal behavior. In most industries several factors influence the productivity of equipment; however, some are obviously recognizable factors earlier to process, meanwhile others are unanticipated and affect equipment productivity negatively [23].

Best manufacturing practices What do the best-performing companies do?

Best manufacturing practices What do the best-performing companies do?

Combination of quality, flexibility and speed. Companies with a high performance improvement in quality-flexibility-speed appear to be able to achieve that by implementing process focus, pull production and environmental compatibility. This confirms the picture starting to emerge, namely that these three action programmes taken together produce a range of different performance effects. The fourth apparently rather influential action programme, equipment productivity, does not have significant influence on Q-F-S improvement, and the question is why. We do not have an answer. Combination of quality, flexibility and cost performance. Programmes directed towards process focus, pull production, equipment productivity and environmental compatibility are positively related to improving quality-flexibility-cost performance. The essence of the explanation has been given above.

Accounting for Changes in Between-Group Inequality

Accounting for Changes in Between-Group Inequality

In this section we summarize our baseline results, quantifying the implications for rela- tive wages of changes in labor composition, occupation shifters, equipment productivity, and labor productivity. We construct various measures of changes in between-group in- equality that aggregate wage changes across our thirty labor groups (e.g., the skill pre- mium). As is standard, when doing so, both in the model and in the data, we construct composition-adjusted wage changes; that is, for each aggregated measure we average wage changes across the corresponding labor groups using constant weights over time, as de- scribed in detail in Appendix A. For each measure of inequality we report its cumulative log change between 1984 and 2003, calculated as the sum of the log change over all sub- periods in our data. 31 We also report the log change over each sub-period in our data. Skill premium. We begin by decomposing changes in the skill premium over the full sample period and over each sub-period, displayed in Table 3. The first column re- ports the change in the data, which is also the change predicted by the model when all changes—in labor composition, occupation shifters, equipment productivity, and labor productivity—are simultaneously considered. Between 1984 and 2003 the skill premium increased by 15.1 log points, with the largest increases occurring between 1984 and 1993. The subsequent four columns summarize the counterfactual change in the skill premium predicted by the model if only one component is changed (i.e. holding the other compo- nents at their t 0 level).

Industrialised building system formation scheduling for public buildings

Industrialised building system formation scheduling for public buildings

Based on Figure 1.1, we can see that our construction industry’s highly dependency on untrained labours has led to the high usage of unskilled and cheap foreign workers. This has prompted the current construction industry to be labour intensive, due to the high usage of unskilled workers in the construction field. Taking into account of the high usage of foreign unskilled workers at site, it is difficult for the construction sector to achieve high productivity of work at site.

The changes of radiotherapy in Lithuania: infrastructure, utilization rate, and cost

The changes of radiotherapy in Lithuania: infrastructure, utilization rate, and cost

In conclusion, during the  recent thirteen years, RT services in Lithuania have dramatically improved, but we are still behind the average of European coun- tries and benchmark rates. This potential need for ad- ditional new equipment and the workforce required to support it represents a significant challenge over the coming years and needs to feed into trust capital planning and workforce strategies as early as possi- ble. The reimbursement system in the country is not in favour of RT centres. In order to raise the RT utili- zation rate, the reimbursement mechanism has to be reviewed and optimised. We think that this overview of the Lithuanian RT infrastructure will help to as- sess the current situation and continue the successful development of the RT services by increasing their accessibility and high quality.

Analysis of Productivity Measures and the Factors Affecting Accurate Measurement of Productivity

Analysis of Productivity Measures and the Factors Affecting Accurate Measurement of Productivity

Within a complex product mix environment it may however be quite relevant to analyze the productivity of setup changes to identify areas for improvement. A general comparison of setup productivities for commodity products versus complex products is not necessarily useful just as comparing the productivity of setup changes in a plant producing extremely long runs of the same product with a plant running many short runs is not necessarily beneficial. This is relevant because the product mixes being run at the plants may be different and affect the measurement of productivity because a sateen fabric would have different stop levels than plain sheeting fabrics. In these cases the specific product mix needs to be analyzed to determine which areas of the process are most critical to the overall success of the operation because if a plant is running more of one kind of a product then the setup changes are relatively lower than a plant that is running a homogenous mix of different products. Specifically designed productivity measures for these aspects can then help in identifying areas that are candidates for improvement such an example is shown in figure 7.

Composition of Capital and Gains from Trade in Equipment

Composition of Capital and Gains from Trade in Equipment

Quantitatively, equipment trade is important for capital composition. The fall in equipment trade barriers during the period 1985-2005 accounts for 30 percent of the increase in the equipment capital share in rich and 32 percent in poor. This is the first contribution of this paper. With lower trade barriers, rich countries specialize in equipment and reap efficiency gains. Poor countries benefit by trading their comparative advantage good for equipment, which is inefficiently produced at home. Second, I examine the channels through which equipment trade affects incomes. The 1985- 2005 fall in equipment trade costs resulted in higher incomes in all countries. I quantify a novel channel, namely capital composition, through which income gains are transmitted. The capital composition channel accounts for 35 percent of the income gain in rich and 64 percent in poor. This channel is quantitatively more important for poor countries and rich countries gain mainly through increases in total factor productivity (henceforth, TFP). To the best of my knowledge, this is the first paper that studies the role of equipment trade in the cross-country composition of capital and quantifies channels through which countries gain from trade.

Decision Making for Purchase/Rental of Road Construction Equipment based on Productivity and Owning & Operating Cost

Decision Making for Purchase/Rental of Road Construction Equipment based on Productivity and Owning & Operating Cost

Construction equipment is one of the biggest investments carried out in the construction industry. Almost 15-30% of the total project cost has been accounted for plants and Machinery. [1] One must have Knowledge about owning and operating cost and productivity (25% less than given in the company’s manual) [2] before equipment utilization. Also, monitoring of actual owning and operating cost of equipment on a regular basis is necessary for profitability. Fact is, even today many of the contractors aren’t well educated and hence they can't decide whether to own or rent the equipment for fulfilling the needs in the construction project. Also, they are unable to judge whether owing will be profitable or renting.

Economic results of agricultural companies in production and marginal areas in the year 2000

Economic results of agricultural companies in production and marginal areas in the year 2000

The level of the productivity of labour in the moni- tored period can be characterized by two different time segments. The first one is the period 1995–1997, the sec- ond one 1997–2000. The first time segment is character- ized by the productivity of labour 400 000–500 000 CZK, (with some exceptions of 500 000–600 000 CZK). Also the annual growth is relatively small. The second peri- od is characterized by a considerably higher productiv- ity of labour: 600 000–800 000 CZK and in 2000: 700 000–840 000 CZK. The productivity of labour is an important indicator which shows that an important change is under way in the particular monitored period. In production areas, the growth rate of the productivity of labour was 175.27%, in marginal areas, it was 159.34%. The lower growth rate in marginal areas was probably caused by the decrease of revenues in agricultural com- panies.

Total Productivity at Firm Level: A Case Study of a steel Manufacturing Company in Osun State, Nigeria

Total Productivity at Firm Level: A Case Study of a steel Manufacturing Company in Osun State, Nigeria

Abstract: Productivity performance has always been an important aspect in manufacturing. This measurement is essential to benchmark and improve a company’s performance. The total output could be regarded as the measure of performance of manufacturing firm with labour productivity as main contributing factor. This has led to manufacturing firm neglecting other measures of productivity. The total productivity of a steel manufacturing firm was determined for a period of five years using Craig and Harris model. The analysis carried out showed that years 2005 and 2008 had the lowest and highest total productivity level respectively. The computed partial productivity for these years are Labour = 4.87; 4.98 Capital = 4.76; 5.60 Raw Material = 5.76; 6.38 while the productivity P t

fer significantly in how labor and capi- tal services are measured in calculat- ing multifactor productivity. For exam- ple, the Bureau of Economic Analysis explicitly accounts for worker quality in terms of worker experience, educa- tion, and sex, while Statistics Canada does not. Compared with the U.S. approach, Coulombe (2002) finds the Statistics Canada approach led to an overestimate of the growth of quality- adjusted hours worked in Canada in the 1960s and the early 1970s but gen- erated an underestimate of quality- adjusted hours worked in the mid- 1970s through late 1990s. Land and inventories are not counted in the Canadian capital stock but are includ- ed in computing the U.S. capital stock. According to Coulombe, the largest source of difference in the multifactor productivity numbers is Statistics Canada’s use of higher rates of overall asset depreciation, especially in the early years of assets. The higher rate of asset depreciation generates a smaller estimate of the capital stock, particularly in times of recent strong growth in business investment. To remove these data inconsistencies, Coulombe recommends that Statistics Canada adapt the U.S. methodology in computing multifactor productivity. Appendix figure 8
