This study aimed to improve the transportation management of a case study company which produced seasoning powder. Recently, they had two main problems in logistics department: high transportation cost and long vehicle scheduling time. Thus, the objectives of this study were to reduce transportation cost and scheduling time. Due to the delivery in Bangkok and metropolitan area, this problem became the vehicle routing problem with time windows. Then, we proposed a three phases-heuristics which composed of clustering, vehicle allocation and vehicle routing. In the first phase, we applied mapping to visualize the locations of customers. Then, the experts determined how to cluster the customers. The benefit of this phase was to reduce the problem size. In the second phase, the customers in each zone were allocated to the truck. Due to the distribution in Bangkok and metropolitan, there was a time windows constraint for some customers. Hence, we formulated the integer programming to minimize the number of vehicles used since the company outsourced the transportation to the third party logistics (3PLs) or the logistics providers who charged the fixed cost per truck. Hence, the problem became a bin packing problem with time windows constraints. Then, we used Lingo 6.0 and solver function in Microsoft Excel to solve the problem. Finally, in the third phase, the logistics providers who had experience of the traffic and roads solved the routing problem of each truck regarding the time windows constraint of the customers. The result showed that the monthly transportation cost was reduced by 23% or 37,650 baht per month and computational time was reduced by 67%.

Traditionally, the campus layout planning is based on the architecture theories and pays little attention to the students' convenience. In this paper, we improve the weighting method and the data processing process of Systematic layout planning (SLP). Aiming at providing most convenience for the students, a campus layout planning method is presented based on the improved SLP. With an example about campus extension, this method is introduced in detail.

The response speed of emergency medical services (EMS) is extremely critical for the pre-hospital life saving. For emergency patients, the probability of survival will decease remarkably with each minute passing. Therefore, to provide quick EMS, the location of first-aid stations and the number of ambulances assigned to each station should be carefully designed. This paper focuses on exploring a new method to optimize the distribution of first-aid resources. The double coverage model is partially applied with a new objective function that minimizes expected cost for delayed emergencies plus operational cost for EMS. In the modified model, each minute beyond preset standard is considered as missing time that will result in extra costs, so that patients' emergency demands are much more valued instead of simply “covered”. To solve this integer-programing problem, the ant colony optimization algorithm with fine-tuned parameters is applied. In the paper, the plan for ambulance assignment during daytime is studied with a thoughtful constraint considering emergency staffs' workload. In addition, various combos of potential emergency sites are tested to find the best plan for newly built stations with unchanged number of vehicles. The paper turns out that when increasing the number of first-aid stations from 35 (current number of stations) to 50, the total cost will be significantly reduced. This conclusion suggests that the number of first-aid stations plays a more important role in optimization, or in other words, travel time between demands and emergency providers outweighs. The data of this study come from Shanghai Emergency Center.

Banks have different practices towards big corporations and small enterprises for financing. While these two markets are quite distinct, correlations exist between them. Given its competitive advantages, a bank may perceive certain market as its strategic business. In this paper, we investigate markets that exhibit important “stochastic correlations”. Importantly, the correlated needs have no connection to whether services in the markets are complements or substitutes. By examining the strategic incentive under different market settings, we develop a theoretical model for banking services in which clients are heterogeneous and financial markets are stochastically interdependent. Within this framework, we also look at the impact of government policies on the banks' service decision. This paper points out the incentive issues of the bank operations that may require public intervention. We show that tax policies may affect the operating decision. Government subsidies have no impact but both enhanced profit and sales taxes reduce the benefits from cross-market services.

This paper replaces the relationship between the violation of organizational psychological contract and employees with the relationship between the violation of psychological contract and customers in the context of marketing. Through a quantitative research on 236 customers who have travelled before and structural equation verification, and found, there exist a kind of psychological contract between service firms and customers similar to that between organizations and employees, constituted by a two-dimensional structure which involves transactional psychological contract and relational psychological contract. In the relationship between service firms' violation of psychological contract and customers' ECLS behavior, customers' degree of satisfaction plays a partly intermediary role. We also found out that the violation of transactional psychological contract directly results in customers' quitting using the service, increasing complaints and customers' decreasing loyalty and silent reaction, and indirectly causing the decline of customers' degree of satisfaction. At the same time, the violation of relational psychological contract only brings about influence on customers' loyalty.

Using a real case with 161 samples, we investigated the relationships among relationship property, service innovation, co-production, and innovation orientation in service industry of Pearl River Delta of China. The empirical results demonstrated that co-production mediated the relationship between relationship property and service innovation, and that innovation orientation moderated the relationship between relationship property and service innovation. These findings can be applied to improve communication among employees, enhance production cooperation and promote service innovation.

Among most of product planners in manufacturing companies, it has been believed that there must be some common elements or factors in successful product planning processes. There seems to be, however, no established general theories or common frameworks in product planning practices yet. Those who created successful products are considered as unusual people having special talents. However, it is obvious that even those gifted product planners sometimes made mistakes and launched disappointing products into the marketplace. Though they must have learned something from those failures and must have fine-tuned or even reconsidered them from scratch in the next new product planning processes, which were usually well accepted, they have never revealed what they learned and how they redesigned them. Our hypothesis is that they intentionally or unintentionally implement the anticipated “value in use” into their products so that their target customers easily appreciate intangible service values rather than products themselves as vehicles. This paper is a first step towards better understanding for successful product planning process by analyzing actual four product planning cases in the aspects of Service Dominant Logic in which value in use is conceptually clarified.
