Improving overall equipment cost loss adding cost of quality

This research has the objective of improving indicators for evaluating losses of equipment. It also proposes a newly developed computing methodology for estimating the quantitative losses in monetary unit. The presented methodology is to calculate losses following overall equipment effectiveness (OEE) consisting of opportunity and production cost losses and also from cost of quality (COQ) approaches. This method eliminates some of OEEs weaknesses and expands scope from overall equipment cost loss (OECL). The proposed calculating methodology is demonstrated by applying to a real manufacturer of equipment. This newly improved model can prioritise problematic equipment more appropriately than OEE and OECL.

An efficient resource allocation in strategic management using a novel hybrid method

– The purpose of this paper is to suggest a novel hybrid method by integrating a decision sciences approach with balanced scorecard (BSC) in order to scientifically enable the efficient strategic management of an organization under limited resources. The proposed research model endeavors to improve critical basis deficiencies of the original BSC as well as formerly improved forms of BSC by appropriately integrating three disparate methods: BSC, analytic network process (ANP), and zero-one goal programming (ZOGP). , – The designed approach is separated into three major parts. At first, the traditional BSC, concentrating on both financial and intellectual capital, was adopted as the strategic management framework, and then priorities as well as the importance of tactical drivers derived from BSC application were consecutively identified by the application of ANP. Finally, the study further applied the obtained results of integrated BSC and ANP to ZOGP in order to scientifically identify the optimal strategic investment under simulated constraints of the considered organization. , – An application of BSC, ANP, and ZOGP with a case study of an academic institution provided an improved strategic management approach for optimally and scientifically utilizing the limited resources of the organization. The suggested results indicated that only 11 of the 23 strategic projects should be executed. Moreover, the selected tactical tasks would efficiently use less than 36 percent of the strategic expenses of the traditional management approach. , – Based on the intensive literature reviews, the proposed method could be determined as a novel hybrid approach. It newly conveyed the practical management approach by innovatively including the proper decision sciences method to BSC. This improvement scientifically considered on the resource allocation process that has never been studied before in formerly improved BSC.

Overall Weighting Equipment Effectiveness

This research is designed to improve the original Overall Equipment Effectiveness (OEE). The OEE is the process, in which acquired to specify an equivalent weight setting of every single element, even though; each concerning losses are totally different. Hence, the study proposes a simpler weight setting method, so called the Rank-Order Centroid (ROC), to identify dissimilarity in weighting each OEE element. The ROC methodology is easier to determine the weight than the existing weighted OEE method, which is based on an analytical hierarchy process. This newly calculating methodology is the Overall Weighting Equipment Effectiveness (OWEE). It is presented and also implemented in a fiber cement roof manufacturer. The result granted from OWEE, however, is different from those of the original OEE and of the existing weighted OEE.

An analytic network process approach for the election of green marketable products

Purpose – In this study, an optimal green product is selected from three newly developed ecological products and a non-environmentally friendly product. An analytic network process (ANP), used widely for multi-criteria decision making (MCDM), is applied to account for the tradeoff issues among the criteria (quality, cost and green issue) in the new green product selection processes. The paper aims to discuss these issues. Design/methodology/approach – This paper focuses on current social and consumer requirements. New product selection processes consider three major perspectives, i.e., quality, cost and environment, as criteria. The following two main methods are applied to respond to this multi-disciplinary issue: the eight quality dimensions proposed by Garvin are used to manage the quality issue, and a life cycle costing (LCC) method is applied for consideration of the cost and green issue. Therefore, the dependency issue among the criteria is considered, using a suitably selected method, the ANP metho...

Implementation of overall equipment effectiveness in wire mesh manufacturing

This study presents the implementation of overall equipment effectiveness (OEE) at a small enterprise manufacturing wire mesh in the developing country of Thailand. This company had never established any performance measurement before. Therefore, an appropriate indicator was elaborately selected for the case study, and OEE was chosen. OEE is employed as a simple indicator, but it is still an effective method for analyzing the efficiency of a single machine and an integrated machinery system. The case study of OEE was carried out from set-up stage to full implementation. Several processes were carried out to establish the OEE indicator. OEE helped the company identify the primary problems concerning the availability rate and performance efficiency. The management made the decisions by relying on OEE results and its details, and mandated the elimination of the root causes of breakdown losses and speed losses. Finally, after six months of full implementation, OEE performances improved by over 60 percentages, since availability rate and performance efficiency were improved over 75 percentages, and quality rate was maintained at the same level.

Implementation of the overall equipment cost loss (OECL) methodology for comparison with overall equipment effectiveness (OEE)

Purpose – The purpose of this paper is to describe the overall equipment cost loss (OECL) methodology and an implementation of this methodology, to compare the outcomes of OECL with those of overall equipment effectiveness (OEE), and finally to identify the benefits offered by this new methodology. Design/methodology/approach – The proposed methodology, OECL, combines six large loss models and a financial model in the performance evaluation of equipment. The six large losses are converted into monetary units. OECL is a new way of evaluating equipment performance that differs from the original OEE methodology and overcomes some of the limitations of OEE. This new methodology can be used to rank problematic machines by accounting for production elements together with finance elements. Findings – The OECL and OEE methodologies rank problematic machines differently. Research limitations/implications – Efforts were made in this research to identify factors affecting OECL outcomes, but it was found that it was ...

Use of an Analytic Network Process and Monte Carlo Analysis in New Product Formula Selection Decisions

One crucial matter in routine life is decision-making. Although decision-making in everyday life appears to be easily dealt with by one-on-one comparisons, the same is not true with decision-making in business. In business management decisions, problems are more complicated than those in individual life because most business situations fall into the category of multi-criteria decision-making (MCDM) problems. Therefore, appropriate multi-criteria decision methods should be carefully selected to solve these problems. This study uses the analytic network process (ANP), one of the widely available multi-criteria decision methods. However, this popular method generally ignores the uncertainty inherent in the input data. Therefore, this paper proposes an improved process that considers uncertainty by using Monte Carlo analysis with input values then applied to the ANP procedures. This proposed method is implemented by a real business that produces roof tiles; the primary goal of the study is to select among newly developed roof formulas by considering the uncertainty and interrelation among decision criteria and elements as well as alternatives. The outcomes of study accurately rank the new product formulas. Furthermore, the results of improved method differ the rankings produced by the original ANP. The observed dissimilarities mainly result from uncertainty consideration discussed in this study.

A Framework for New Product Selection Decision Using Analytic Network Process and Knowledge Management

This paper aims to propose a new framework applying analytic network process (ANP) considering with three currently crucial perspectives; quality, environment and cost. At the same time of the ANP processes, a knowledge creation process and also knowledge evaluation method are considered for sustaining and measuring new emerging knowledge from proposed framework. This study provides a rational of this comprehensive framework and selected methods; those are ANP, eight quality dimensions of Garvin, life cycle costing (LCC), socialization, externalization, combination and internalization (SECI) model and Skandia model. All concerning methods are discussed and argued of their potential benefits and strengths delivering to the proposed framework.

A literature review on performance measures of logistics management: an intellectual capital perspective

Today, logistics management requires a comprehensive set of performance indicators that measure both tangible assets and intellectual capital (IC) of organisations. Nevertheless, most of the measures used in the past mainly related to the financial aspect, although some specific components of IC, such as process efficiency and effectiveness, have been considered. Logistics literature lacks a comprehensive consideration of the diverse IC measures, and it is unclear which area of IC requires more focus and development. Therefore, to explore and identify an opportunity for improvement, this study reviews the academic literature related to IC measures in logistics management. This literature review considers 111 academic articles published between 1994 and 2016. Following the six dimensions of the IC-Index, all indicators obtained from the literature are classified according to IC elements. The key contribution of this review is that it addresses the following gaps in the literature: the limited adoption of comprehensive IC methods in logistics studies; underdevelopment of specific indicators and measures used; failure to consider all human capital as well as renewal and development elements; and, finally, lack of academic research considering the influences among the different IC elements and logistics and financial performance.

Determining key performance indicators of intellectual capital in logistics business using Delphi method

The objective of this study is to construct a model of intellectual capital management for improving its traditional management process by using the Delphi method. The research approach has been focused on identifying indicators that are important to the achievements of the business performances with the participatory assessment of several experts in the organization. This has been done for avoiding any bias that might occur from the evaluation by a particular management. The conceptual model of this research has been applied to a real business of which intellectual capital need to be developed, particularly in todays logistics industry. The research results show that the suggested model can help the organization determine the important intellectual capital indicators at suitable numbers in managing logistic business. In addition, the proposed process and results can also be applied to further development in enabling organizations to manage its business within limited resources more efficiently.
