Maturity models are a useful way for an organisation to assess their processes and the overall maturity levels of the organisation. However, finding the most appropriate maturity model is not an easy task especially for practitioners in industry. Hence, the purpose of this paper is to critically review, compare and contrast the existing maturity models in quality/operations management topics. This...
With the manufacturer with mass customization paradigm extending its scope into global manufacturing network, module-based product family configuration and supply chain design should be simultaneously considered. This paper formulates joint optimization of product family and supply chain configuration as a leader-flower Stackelberg game. Product family configuration is modeled as a upper level problem...
Differential Evolution is a population based optimization technique which discretizes the sample space of solution based on generations of population members and performs a fitness evaluation to determine the best population members. The fitness evaluation process involves lengthy calculations, thus becoming the most redundant and time consuming aspect of the program. The aim of the proposed work...
A dynamic fowshop, where new job orders continuously arrive over the scheduling horizon, is considered in this study. The objective is to minimize the mean deviation from the due dates for the completed jobs. A cooperative dispatching approach is investigated for this objective, and its performance evaluated by comparison with other dispatching rules. The results from the comparative study indicate...
Taking into account imprecise and incomplete information is very important for properly making a decision under uncertainty. However, due to inherent mechanism, many traditional approaches cannot deal with such problems. Motivated by this point, we propose a proportional fuzzy linguistic distribution model for decision making under uncertainty. It is shown that this new model not only allows experts...
The identification of attributes attractive for users is essential for creating a positive user experience with a product. For this, Kano's method classifies customer needs into different categories. Besides the attractiveness, the attribute's importance for the customer might be also relevant for User Experience. Thus, we combine Kano's method and the conjoint analysis for the identification of attributes,...
Knowledge transfers across projects in Project-Based Organizations (PBOs) are more complex and challenging than in the permanent organizational context due to the temporary nature of project teams in which team members do not see capturing and transferring across projects as important for long term benefits to the organization. Although knowledge transfer is well researched, few empirical studies...
Optimization of tool path planning using metaheuristic algorithms provides a feasible approach to reduce geometrical machining errors in 5-axis flank machining of ruled surfaces. The solution quality of these algorithms is unsatisfactory in a high-dimensional search space. In this study, various algorithms derived from the electromagnetism-like mechanism (EM) were applied. The test results of representative...
The influence of online store belief and product category on impulse buying was investigated in this study through empirical research. Path analysis technologies were applied to evaluate the research model based on the survey. The results showed that the consumer impulse buying for both hedonic and utilitarian products was influenced by the online store belief. This study will provide theoretical...
The performance of any technological system is dependent on the performance of its subsystems. The evolution of the entire technological systems performance is determined by the performance improvements in deficient sub-systems. In this paper, we extend earlier notions of clockspeed measurement [6, 7] in our examination of the evolutionary dynamics of technological systems. We study the time lag in...
This study presents the construction of a human reliability model for assembly line manual workers, using Cox's Proportional Risk model. Nine factors were identified in 120 assembly line operators using psychometric tests. Subsequently, the factors of stress, motivation, memory, and personality were identified, using a multiple linear regression analysis, as those that significantly contribute to...
In this industrial engineering study working postures of 57 workers in an assembly of a trailer manufacturer were analyzed according to the OWAS method and its extension to head postures. For eight especially stressful work tasks 19714 body postures were analyzed. Overall the working posture analysis identified a largely acceptable postural load. A significant influence of the work task on relative...
Global supply chain management has an important role for globalization of marketplaces and global production. The production and distribution planning for suppliers and retailers with different objectives should be coordinated to minimize the total costs. However, it is well-known that the equilibrium solution for decentralized decision making is inferior to the solution of centralized problem. This...
The nuclear industry has established stringent controls to ensure that electricity is produced in a safe and reliable manner and as such, it is expected that a nuclear power plant is operated safely, adheres to nuclear codes and standards, specifications, processes and procedures and implements projects and modifications of a high quality indicating a successfully operated plant. Project quality is...
Main objectives of this work are to describe the current situation and increase the understanding of successful Six Sigma (SS) implementations through a study of Critical Success Factors (CSFs) reported by researchers and practitioners. The work integrates lessons learned from successful projects and considers additional progress to the approach, through an extended literature review. In order to...
It's obvious that any manufacturing system is undergoing increasing deterioration owing to usage, age and stochastic failures. Frequently, this deterioration results in the product quality degradation and hence entails a significant nonconforming cost "NCC" as well as a maintenance cost. This paper investigates the relationship between maintenance and quality by developing an economic strategy...
In this paper, we present the conceptual framework of human values identification and assessment for total quality management (TQM) implementation. Human values are the guiding force and critical to explore for TQM implementation and their importance have long intrigued researchers. However, literature lacks any direction for required human values identification and assessment for TQM implementation...
Organisations which achieve high levels of performance against quality and business excellence award criteria still face challenges in sustaining their efforts. This paper has therefore set out to identify and analyze the driving ‘soft’ factors affecting sustaining quality excellence within the United Arab Emirates business environment. The paper uses survey data from 138 Dubai Quality Award recipient...
This paper presents a method for the improvement of economic performance of biofuel supply chain. A mathematical model is proposed for optimal planning of biofuel supply chain in order to minimize the total operational costs. The model is linear and takes into consideration the availability of feedstock and biorefineries and determines the optimal schedule for harvesting and transportation of biomass...
Especially the early phase of the innovation process, the planning phase, is characterized by extensive decisions and a wide range of uncertainty. Hence, it is essential for product designers to understand future Product-Service System characteristics and prospective properties. Thus, in this paper we present a framework for depicting a Product-Service System model throughout the planning phase of...
