Productivity and Efficiency in the Development of the Swedish Construction Sector  [PDF]
Anne Landin, Mats Oberg
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.46038

The measurement of productivity and efficiency of activities in the Swedish construction sector is examined. Understanding past and present levels of productivity is necessary to steer emerging and future developments aimed at increasing efficiency of construction. The absence of purposeful measurement methods and tools for determining current and targeted levels of productivity creates confusion for clients, designers, constructors and end-users, who are unable to make confident forecasts of costs and revenues or benefits over project life cycles. The findings of an investigation using panels of expert practitioners guided by senior researchers revealed shortcomings in the understanding of factors of driving productivity as well as uncertainty over where improvements might be achieved. The significance of the findings is that methods and tools must be calibrated to current and emerging construction practices and their technical bases rather than continuing with measurements that were conceived for earlier processes and products. The paper concludes with an outline of further research aimed at improving self-learning in regard to both process and product as part of a broad response to raising efficiency through innovation.

Abstract: Currently a large effort is being done with the intention to educate people about how much energy each electrical appliance uses in their houses, since this knowledge is the fundamental basis of energy efficiency programs that can be managed by the household owners. This paper presents a simple yet functional non-intrusive method for electric power measurement that can be applied in energy efficiency programs, in order to provide a better knowledge of the energy consumption of the appliances in a home.
The Efficiency Measurement of Indonesian Universities Based on a Fuzzy Data Envelopment Analysis  [PDF]
Umi Mahmudah, Muhamad Safiih Lola
Open Journal of Statistics (OJS) , 2016, DOI: 10.4236/ojs.2016.66085
Abstract: The main objective of this study is to measure the relative efficiency of Indonesian universities in 2015. There are twenty five DMUs with four inputs and five outputs that are analyzed. Due to the low number of Indonesian scientific publications, this study analyses the performance of the top 25 universities based on the Webometrics ranking as it has been used as one of the indicators of university achievements by the Higher Education of Indonesia. The Data Envelopment Analysis (DEA) is used to obtain the scores of efficiency, while the Fuzzy approach is applied to address the possibility of errors from the auditor’s assessment in determining the input and output variables correctly. The FDEA can be used in measuring the universities performances under imprecise inputs and outputs. Both the CRS (constant returns to scale) and the VRS (variable returns to scale) models are presented. The empirical results show that 36 percent of universities perform efficiently on the CRS model while 52 percent of universities have efficient performances under the VRS model. Furthermore, the well-known universities have shown relatively low scores, which indicate they need to improve their performances in publishing scientific work, as well as providing useful information to the public through the official websites. Generally, the results of the VRS model are better than the CRS model for both the DEA and the FDEA methods.

Water , 2010, DOI: 10.3390/w2030461
Abstract: Smart metering technology for residential buildings is being trialed and rolled out by water utilities to assist with improved urban water management in a future affected by climate change. The technology can provide near real-time monitoring of where water is used in the home, disaggregated by end-use (shower, toilet, clothes washing, garden irrigation, etc.). This paper explores questions regarding the degree of information detail required to assist utilities in targeting demand management programs and informing customers of their usage patterns, whilst ensuring privacy concerns of residents are upheld.

Management Science Letters , 2012,
Abstract: Measuring organization performance plays an important role for developing better strategic plans. In today's competitive environment, organizations attempt for the product quality or offering the service, delivery, reliability capability and the customer satisfaction. These properties are not measurable only by traditional financial criteria and we need a method, which could consider non-financial factors as well. The present study of this paper proposed a hybrid of balanced score card (BSC) and data envelopment analysis (DEA) method for an empirical study of banking sector. The study proposes a model for assessing the Tose`eTa`avon bank performance, which is an example of governmental credit and financial services institutes. The study determines different important factors associated with each four components of BSC and uses analytical hierarchy process to rank the measures. In each part of BSC implementation, we use DEA for ranking different units of bank and efficient and inefficient units are determined.

Abstract: One of the most important tools for improving the relative efficiencies of any organization is to establish suggestion system. Having a reliable system, which could reflect all employees’ comments and concerns, helps managers take necessary actions to remove any possible obstacle in the system. In this paper, we measure efficiency and effectiveness of suggestion system in the National Iranian Oil Products Distribution. We also provide practical suggestions for improvement and necessary actions required to review the system. The proposed study of this paper uses a sample of 297 people from 1294 employees who work in different position for some of the regional offices of this firm in north part of Iran. The study has used two separate questionnaires, where the first one consists of 40 questions in Likert scale trying to measure the efficiency and effectiveness of the suggestion system. In addition, we use another questionnaire to rank important factors detected in the first stage. The results of questionnaires have been analyzed using different statistical tests.

International Journal of Materials, Mechanics and Manufacturing , 2013, DOI: 10.7763/ijmmm.2013.v1.19
Abstract: Food and agricultural production in Thailand play an indispensable role in economic growth. The frozen vegetable industry is considered to be important due to its increasing annual exports. The goal of this paper is to measure the efficiency of export frozen vegetables using network DEA. We use the two-stage model to measures efficiency by separating the supply chain structure into suppliers and manufacturers. There are 12 criteria used for inputs and outputs. The results show that out of 8 organizations with supply chains, only 2 chains are efficient according to the BCC-O model and only 1 chain is efficient under the CCR-O model. However, if the manufacturer’s role in the supply chain is considered, the results show that the majority of these manufacturers are efficient.

Abstract: Performance evaluation plays an important role in determining faults and difficulties of any organization as well as attempting to increase capabilities and improve activities. Data envelopment analysis (DEA), as a non-parametric method, has been one of the most important and significant management tools for measuring output or efficiency. In this paper, we propose a method to utilize balanced score card (BSC) as a tool for designing performance evaluation indices of an organization. The integrated BSC-DEA has been applied as an empirical case for a major private bank organization and the results are analyzed.
