The objective of this study is to find a sequence of jobs for the permutation flow shop to minimize makespan. A feed forward back propagation neural network is used to solve the 10 machine problem taken from the literature. The network is trained with the optimal sequences for five, six and seven jobs problem. This trained network is then used to solve the problem with greater number of jobs. The...
The purpose of this article is to define an approach to improve consideration of users' requirements in the early stage of a construction project. The input of the approach is the construction project appraisal and aims to produce a briefing program add-on relative to its business process needs and objectives. Requirements engineering is used as a basis for the proposed methodology, supported by the...
This paper has been conducted with the aim to focus on hotel service quality based on 29-characteristic indicators applied from SERVQUAL model by comparing two hotel types namely, (1) the boutique hotel and (2) the business hotel in Thailand. This paper also aims to study the expectation, perception and gaps between customers' expectation and perception on hotel services quality. The key findings...
Hierarchical facility location problems with three levels deal with location of facilities in any level and assignment traffic to given routing. Hub covering problems covered the demand nodes, if they are within a particular radius of a facility that can supply their demand. This paper study the single allocation hierarchical hub maximal covering problem over complete network linking in the first...
The reality of healthcare delivery in emerging societies are not good enough for most of its population. This article aims to explore how the analytical and monitoring capabilities of information systems know as BPMS (Business Process Management Systems) could improve the quality of services provided in Brazil. We propose that the adoption of a service science and process-centric view will be of great...
The use of portable device like pocket PCs and smart phone to support teaching and learning is not a new concept. Although the variety of mobile platforms provide more flexible and extendable learning experience, the various hardware restrictions consequently become the unavoidable challenges and barriers we need to overcome. In this paper we focus on: (1) improving the learning performance by prefetching...
The problems of entropy functions maximization over the sets specified with the simultaneous linear or quadratic equalities and inequalities (the problems of entropy-linear and entropy quadratic programming) are under consideration. Multiplicative algorithms with p-active dual and primal variables are proposed for such problems solving. Active variables are selected using the feedback about p-maximal...
Considering the importance of network for technological innovation, this paper takes a new view on technological innovation capability (TIC) and develops TIC indicator system, moreover, it setups a framework for the TIC evaluation in companies. With works on the innovation process and innovation success and failure experiences, it highlights the importance of network for the achievement of technological...
Based on the concept of lean, the consumption cycle of demand channel and supply channel is investigated in this paper. Moreover, the combination of relationship between customer demand, lean service, lean marketing, lean consumption, lean design and lean production is studied to derive the expectative benefit from the application of the consumption cycle model of demand chain in service industry...
A dual displacement measurement meter applied as a compensatory device for spindle thermal growth compensation, it can reduce the measurement error dramatically from single measurement device. The result matches the laser inspection report, which is an external direct checking device and been considered as one of the best checking device of spindle thermal growth. However, the non-flat surface of...
In this paper, we propose a decentralized VPLs based control policy for semiconductor manufacturing. Based on utilizations and entropies, a new classification method is designed to decentralize global objectives into local objectives of workstations. Then a decentralized multi-objective scheduling policy is proposed to control Virtual Production Lines (VPLs). We generate two SMS cases from a test...
Ergonomic evaluation of manually controlled devices is an important means of testing a man - machine interface matching in manned space medicine and engineering research. It's one of the comprehensive evaluation method based on Delphi, AHP and Grey systems. This study proposed a mathematical model combining subjective weights and objective weights, evaluated manually controlled devices quantitatively,...
Situation awareness of operators plays a key role in the safety of a nuclear power plant. The establishment of a situation awareness assessment model (SAAM) is the foundation of an advanced HRA method. The paper firstly ascertains the relation between situation awareness and human reliability analysis and then forms an organization-committed cause-effect conception model. On the basis of the above,...
This research conducts an empirical study on car recalls in the US market. The research uses secondary data from recall websites maintained by public and private organizations. The objectives of the study are to investigate car recall trends and identify the causes and effects of recalls. Analysis shows that the majority of car recalls are initiated by a few car makers that are facing an increase...
The aim of this work is to use simulation and queueing theory to analyze the current status of the check-in process in an airport and identifying ways to improve its performance. In applications involving stochastic events, demand cannot be determined explicitly beforehand. For those applications, computer simulation is often used to predict resource demands. Queueing results provided a first order...
This paper demonstrates the use of Design of Experiments (DoE) coupled with simulation to design a robust and cost-effective intervention in a systematic way. DoE provides a simple and intuitive method to find the optimum settings of the input factors for the most cost-effective intervention. Moreover, DoE addresses the critique that health care simulations unrealistically assume ideal conditions...
In the era of ubiquitous service, the new service opportunity is closely related to user. User-centric approach takes into account user context in new service development. However, attempts to apply user context is insufficient to identify opportunities, since the opportunity is at least user's potential needs, which are not satisfied yet. In response, this paper proposes a “user-centric service map”...
Contingency theorists have developed the basic grammar of coordination theory around the relationship between coordination mechanisms and circumstance like uncertainty, interdependence, work unit size and functional diversity. Recently, conceptual and empirical studies have emerged that offer new opportunities in coordination theory, for instance structure-process modeling. Meanwhile, model building...
Multivariate quality control charts have some advantages for monitoring more than one variable. Nevertheless, there are some disadvantages when multivariate schemes are employed. The main problem is how to interpret the out-of-control signal. For example, in the case of control charts designed to monitor the mean vector, the chart signals show that there is a shift in the vector, but no indication...
The growing trend of business collaboration exerts an extra pressure on global business communities. This collaboration can be evolved in the form of hierarchical and no-hierarchical. In this research, we have considered non-hierarchical collaboration, where manufacturing firms' especially small and medium enterprises (SMEs) enjoy equal power and freedom within their networks. In order to develop...
