This study provides speedup of the 2-Opt and 3-Opt processes by a new method based on Fourier descriptors (FDs) for the planar traveling salesman problem. By treating the planar tour as a closed contour, the proposed FD-based method, which is used as a potential swap identification function (PSIF), can limit the search space of 2-Opt/3-Opt by identifying the potential swap points/cities. In this article, approximate versions of the 2-Opt and 3-Opt procedures are adopted to investigate the performance of proposed PSIF. The experimental results using the proposed PSIF to reinforce the 3-Opt procedure show that the proposed method provides good quality solutions and faster computation.

The purpose of this article is to examine individual differences of various score functions in multiple criteria decision analysis based on intuitionistic fuzzy sets (IFSs). A review of the literature indicates that score functions have been widely used in multi-criteria evaluations from a variety of research fields. There exist several types of score functions to identify the mixed result of positive and negative parts in a bi-dimensional framework of IFSs. However, very few studies have conducted a comparative analysis of different score functions. Considering various perspectives of score functions, this study developed an integrated programming model to cope with the problems of incompletely known membership grades and positivity and negativity biases by utilizing both deviation variables and weighted score functions. An experimental analysis was conducted to examine the relationship between the results yielded from different score functions with discussions on average Spearman correlation coefficients and contradiction rates. Additional discussions are made to clarify the relative differences in the ranking orders obtained from different combinations of numbers of alternatives and criteria and for different importance conditions.

This article presents a group scheduling problem for manufacturing cells, in which parts may visit different cells. By addressing intra-cell scheduling, the sequence of parts within manufacturing cells is determined; however, in inter-cell scheduling, the sequence of cells is obtained. A novel mathematical model is presented for a multi-criteria group scheduling problem in a cellular manufacturing system with respect to a design objective function minimizing the makespan and costs of intra-cell movement, tardiness, and sequence-dependent setup, simultaneously. Obtaining an optimal solution for this type of complex, large-sized problem in reasonable computational time using traditional approaches and optimization tools is extremely difficult. Thus, we develop a meta-heuristic algorithm based on scatter search (SS) to solve the foregoing model. The related results confirm the efficiency and effectiveness of our proposed SS algorithm, which finds good solutions, especially for medium- and large-sized problems.

Carbon nanotube backlight units (CNT-BLUs) offer advantages (including light weight and superior color performance) that cold cathode fluorescent lamp backlight units (CCFL-BLUs) cannot deliver. If these advantages find favor with liquid crystal display manufacturers, CNT-BLUs could possibly replace CCFL-BLUs. CNT-BLU light-emitting arrays are made by a thick-film screen printing process, which can leave dark obstructions within and between pixel areas. Thus, when the pixels light up, CNT-BLU arrays can display dark blotches within one or more pixels. Existing luminance uniformity measurements, such as Video Electronics Standards Association (VESA) or International Organization for Standardization (ISO) standards, are not designed to deal with this problem. These standards are based on the luminance of multiple non-adjacent points on a display; they cannot reflect the luminance change of adjacent pixels, which is important for measuring the uniformity of CNT-BLU. This situation is aggravated since CNT-BLU is still under development and the current luminance uniformity of CNT-BLU still cannot compete with that of CCFL. This study presents a new luminance uniformity measurement, line non-uniformity, for CNT-BLU. This method was compared with VESA and U Formula with respect to human perception. A set of CNT-BLU images with different levels of mottling was presented to 18 participants. The subjective acceptance thresholds for these images were then calculated. The uniformities using VESA, U Formula, and line non-uniformity approaches for these images were also calculated and fitted to the subjective acceptance threshold. The results showed that line non-uniformity was the best to fit the acceptance threshold; its R 2 ranged from 0.80 to 0.92 whereas the R 2 values of VESA and U Formula ranged from 0.00 to 0.49.

This article considers the optimal management problem of a finite capacity M/H2/1 queueing system, in which the unreliable server operates the F-policy. When the number of customers in the system reaches its capacity K ( ), no further arriving customers are allowed to enter the system until a certain number of customers who are already in the system have been served so that the number of customers in the system decreases to a predetermined threshold F ( ). At that time, the server needs to take an exponential startup time and allow customers to enter the system. The F-policy investigates the most common issue of controlling arrival to a queueing system and a startup time is required before allowing customers to enter the system. This system is useful in many potential applications for wireless communication networks, transportation service systems, and production systems. Some important performance measures are derived. A cost model, developed to determine the optimal capacity K, the optimal threshold F, the optimal setup rate, and the optimal repair rate at a minimum cost, is also studied.

This article addresses the unrelated-parallel machine scheduling problem with sequence-dependent setup times for minimizing the work-in-process inventory (WIP) while maximizing the customer service level in a supply chain. The machine availabilities and job releases are considered dynamic. In order to meet a variety of needs of the producer and customers, a mathematical model that conforms to a bicriteria objective has been developed. As the proposed research problem is shown to be NP-hard, a metasearch heuristic based upon tabu search is also developed to solve industry-size problems. Moreover, to evaluate the effectiveness of the proposed search algorithm, the search algorithmic solutions obtained for example problems are compared with that of the optimal solutions of the mathematical model obtained from CPLEX. To the best of our knowledge, this research is the first of its kind attempted for this scheduling problem in a supply chain.

With the increasing emphasis on the service sector in global business, the rise of the new scholarly domain of service science became inevitable. This innovative research domain appears to be a promising discipline in the modern business environment. Although, the term service science was issued by IBM a mere 6 years ago, it rapidly took off as the Council on Competitiveness published the Palmisano Report in that same year, forecasting that services would become the motor of economic development in the years to come. Service science applies a wealth of scientific methods from various disciplines, including management science, cognitive science, social science, computer science, economics, and engineering. As the global service-based economy and its research fields expand, the services, the vehicle of future business growth, will and should be the focus of business-related fields. This special issue comprises papers from the INFORMS 2010 Service Science Conference, organized by the National Taiwan University of Science and Technology, and held on 7–10 July 2010, in Taipei, Taiwan. From 78 submissions, 19 papers having high evaluation scores were selected, and the authors were invited to submit an extended version of the conference paper for further review. After review and revision, seven papers were accepted for publication in this special issue. These papers describe a cross-section of practical application experiences and state-of-the-art research work using service science methodologies across a variety of industrial domains in several countries. Accordingly, outstanding and insightful results are reported in these papers. Recently, commerce-related subjects have stimulated the broader use of computer science along with other state-of-the-art technologies. Any method for analysis derived from the principles gains superiority over others. Accordingly, Mehravaran and Logendran proposed mathematical programming models for the bicriteria unrelated parallel machine scheduling problem with sequence-dependent setup times in a supply chain. Moreover, the authors also built a search algorithm to find optimal and near optimal solutions for the problem, which has been shown to be NP-hard. Their work indicates that their algorithm is capable of producing high quality solutions within a reasonable computation time. Owing to the dramatic expansion of computer science and Internet-based technologies, the management of renewable resources such as human resources may be estimated by IT systems as part of an IT infrastructure library. Consequently, the twin objectives of better fulfilling customer needs and maximizing the efficiency of resources can be achieved.

Despite the tendency among local cultural industries (LCIs) to combine regional characteristics and conscious representation of surrounding communities to achieve multi-functions related to a particular culture, local production, local living, and ecosystems, a creative, systematic, and customer-oriented approach to improve the quality of LCIs has received scarce attention. Therefore, this study establishes a total quality improvement framework based on quality function deployment (QFD) by integrating the Malcolm Baldrige National Quality Award (MBNQA) and a balanced scorecard (BSC). A case study is also performed in I-lan County of eastern Taiwan to demonstrate the effectiveness of the proposed QFD-based approach. Finally, 15 technical requirements are deployed by the BSC based on a MBNQA-based strategy. Moreover, the leading three priorities to enhance the total quality for use in LCI applications include professional skills training, historical culture, and locality globalization, respectively.

E-learning can be broadly defined as content designed for access through electronic communication, such as the Internet, intranets, digital versatile discs, and synchronous and asynchronous modules. M-learning carries the idea of e-learning a step further by adapting its content to handheld devices such as iPods (a digital audio and storage device from Apple Corporation), personal digital assistants, and smartphones. The main objective of m-learning is to provide the learner the ability to assimilate learning anywhere and at any time. The purpose of this article is to establish the state of m-learning in the corporate and education environments, the devices appropriate to m-learning, the advantages and disadvantages associated with m-learning, and the possible future direction of m-learning. Specifically, using the integrative literature review protocol, this article will cover, discuss, and address critical issues of m-learning including definitions, design models, caveats, adoption processes, and future trends.

Traditionally, importance–performance analysis (IPA) is a simple and effective technique that can assist practitioners in identifying improvement priorities for service attributes. However, many issues still exist and are worthy of discussion. First, traditional IPA emphasizes the external customers’ satisfaction, but ignores internal customers’ (employees) achievement. Second, traditional IPA does not provide any information on comparisons with competitors’ performance. Third, practitioners of traditional IPA usually use the sample mean to rate the importance and performance, leading to a great degree of uncertainty due to sampling errors. Based on these considerations, this study attempts to expand the functions of traditional IPA and proposes an expanded importance–performance analysis (EIPA), which not only involves both the perspectives of internal and external customers in evaluating the importance, but also defines two standardized indictors to measure the internal and external service performance. Moreover, an EIPA matrix is constructed which provides managers with an integrated graphical representation based on symbols and locations of indicators.

However, many issues still exist and are worthy of discussion. First, traditional IPA emphasizes the external customers’ satisfaction, but ignores internal customers’ (employees) achievement. Second, traditional IPA does not provide any information on comparisons with competitors’ performance. Third, practitioners of traditional IPA usually use the sample mean to rate the importance and performance, leading to a great degree of uncertainty due to sampling errors. Based on these considerations, this study attempts to expand the functions of traditional IPA and proposes an expanded importance–performance analysis (EIPA), which not only involves both the perspectives of internal and external customers in evaluating the importance, but also defines two standardized indictors to measure the internal and external service performance.
