A multiobjective retail service location model for fastfood restaurants

Traditionally, most existing retail location models largely ignore the behavioral aspect of locational strategies. On the other hand, a few of the existing behavioral models of retail store choice are aspatial at best. This paper designs a multiobjective retail location decision model which not only considers the behavioral and spatial aspects of location scenarios, but also takes advantage of systematic sequential decision process. The model has been applied to solve ‘real-world-like’ fastfood restaurant location problems which were based on the actual data.     

Market share model of rural telephone service

Premium telephone rates, population density, and the grade of telephone service that rural customers choose all vary with distance from the nearest urban center. A survey of 3800 rural subscribers determined their choice of service for alternative prices given the addition of a new service. A two-stage probit model was used to estimate the new market shares for a wide range of conditions. The model was applied, as part of a large-scale revenue/cost simulation system, to the current and forecasted distribution of customers to evaluate the economic impact of numerous pricing and provisioning possibilities.

A location–allocation model for service providers with application to not-for-profit health care organizations

In this paper, we develop and solve a model for the location and allocation of specialized health care services such as traumatic brain injury (TBI) treatment. The model is based on and applied to one of the Department of Veterans Affairs’ integrated service networks. A cost minimization model with service proportion requirements is solved using simulated annealing. Large instances of the model with 100 candidate medical center locations and 15 open treatment units are solved in about 1000 s. In order to test the real-world applicability of our model, an extensive managerial experiment is conducted using data derived from our health care setting. In this experiment, the effects of three critical factors: (1) degree of centralization of services, (2) the role of patient retention as a function of distance to a treatment unit, and (3) the geographic density of the patient population are investigated with respect to the important trade-off between the cost of providing service and the need to provide such service. Our analysis shows that all three factors of the experiment are both relevant and useful to decision-makers when selecting locations for their services.     

A model of the adoption of radio frequency identification technology: The case of logistics service firms

Globalization and advances in information technology represent both realities and opportunities for enterprises in the 21st century. This paper aims to broaden understanding of service innovation as a critical organizational capability through which the adoption of information technology influences firm performance. This study examines how the adoption of radio frequency identification (RFID) technology influences the operational performance of logistics service firms. We develop the RFID adoption model based on the interorganizational information systems (IOS) view of the firm that integrates the various strands of research into the framework. The study draws from the related information technology and interorganizational information systems literatures to explore organizational factors associated with the adoption of RFID. A model of the associations between information technology and interorganizational information systems use, social support, power structure, organizational readiness, procedural flexibility, and top management support is developed, and hypotheses are advanced about the relationships among these constructs. An empirical survey was conducted among 500 logistics service firms in Taiwan. A total of 131 valid observations were analyzed using the partial least squares technique. Results showed that RFID adoption has positive effects on business practices, which in turn improves operational performance. We address the value of certain interactive firm behaviors in RFID adoption and identify related constructs of RFID adoption in terms of their efficiency and value for logistics service firms. These results have implications for both education and practice.     

Pre-recovery emotions and satisfaction: A moderated mediation model of service recovery and reputation in the banking sector

This study examines the mediating role of service recovery judgments between pre-recovery emotions and post-recovery satisfaction, and investigates the role of firm reputation in this mediation context. Using a moderated mediation framework, the authors test the model with data from 366 customers who experienced a banking service failure and complained to a third party. The results show that distributive, procedural, and interactional justice dimensions mediate the relationship between pre-recovery emotions and satisfaction. Firm reputation moderates the relationship between emotions and satisfaction via distributive and interactional justice, but not via procedural justice. This study provides evidence for the notion that pre-recovery emotion is an antecedent of service recovery process and firm reputation plays an essential role in this process.     

Exploring team mental model dynamics during strategic change implementation in professional service organizations. A sensemaking perspective

The purpose of this paper is to provide a deeper process understanding of team mental model dynamics in a context of strategic change implementation. To do so, we adopt a change recipient sensemaking perspective with the objective to identify salient determinants of team mental model dynamics. We aim to contribute to the managerial and organizational cognition literature by identifying critical micro-foundations that shape team cognition and interpretation processes during strategic change implementation. This adds to the field’s understanding of the under-researched collective dimension of strategic processes in general and strategic change implementation more specifically. Through an explorative case study conducted at a professional service organization, we identified five determinants of team mental model dynamics: coherence between ostensive and performative aspects of organizational routines, equivocality of expectations, dominance of organizational discourse, shifts in organizational identification and cross-understanding between departmental thought worlds. Case findings reveal that implementation processes of strategic change become intricate and difficult if change recipient sensemaking is not effectively acted upon. The five determinants identified require adequate managerial attention in order to avoid slipping into organizational inertia. As a consequence, professional workers are unable to ‘drop their tools’ and fail to integrate the strategic change effort in updated team mental models.     

A successful physician referral service.

Developing a successful hospital-based physician referral service can create a win-win-win venture involving the hospital, its medical staff, and the community at large. As a marketing tool for the hospital, it effectively targets two of the hospital's most important markets: physicians and the consumers of health services, the general public.     

Multi-objectives exception management model for semiconductor back-end environment under turnkey service

On-time delivery is the need for customer satisfaction which is a critical factor in the survival of the semiconductor industry. The on-time-delivery performance of the whole semiconductor turnkey service depends on the performance of the back-end factories. Unfortunately, undesirable and inevitable production variations make it difficult to maintain and improve a factory's performance and more objectives such as cycle time, throughput rate and the due-date accuracy need to be simultaneously considered. This paper presents an exception management model in order to compromise the contradicting needs of delivery accuracy, throughput rate and cycle time. The exception model can be divided into three parts: (1) an integrated performance index is proposed to compromise multiple performance measures; (2) an AWDL (available WIP deviation level) determination model is designed to gather proper AWDLs for triggering exceptions and (3) a WIP correction action is proposed to make abnormal WIP levels back to normal levels as soon as possible. To evaluate the proposed WIP exception management model, a simulation model is constructed and experiments are then conducted. The simulation results show that the proposed model helps back-end factories to set proper exception triggering conditions, reduce uncertainty occurrences and achieve better performances on due dates.     

A parameterized perspective on packing paths of length two

We study (vertex-disjoint) packings of paths of length two (i.e., of P ₂’s) in graphs under a parameterized perspective. Starting from a maximal P ₂-packing ℘ of size j we use extremal combinatorial arguments for determining how many vertices of ℘ appear in some P ₂-packing of size (j+1) (if such a packing exists). We prove that one can ‘reuse’ 2.5j vertices. We also show that this bound is asymptotically sharp. Based on a WIN-WIN approach, we build an algorithm which decides, given a graph, if a P ₂-packing of size at least k exists in time O^*(2.448^3k)\mathcal{O}^{*}(2.448^{3k}) .
