  • A framework of consumer participation in the energy management of a smart
    • Authors: Ti Wang, Daiki Yamashita, Ryuichi Yokoyama, Takahide Niimura, Hiroshi Takamori
      Pages: 217 - 236
      Abstract: This study aims at modelling a dynamic price-based management of the electrical energy needs of a community. A smart community we envision operates a portfolio of power generating facilities including renewable sources. A challenge is how to meet volatile and fluctuating demands via the dynamic pricing. We design a framework to implement the principle: 'Let the consumer be part of the optimiser'. We attempt to capture consumers' responsiveness to the price reflecting the tightness of demand and supply balance. An example here of the model community demonstrates that the dynamic pricing via a complementarity-based modelling approach invites consumers to respond and participate in enhancing efficiency in line with their own preferences.

  • New product development operational performance and its influential
           factors: cross-national comparison between Japan and China
    • Authors: Jingjing Gong, Norio Irikura, Sadami Suzuki
      Pages: 237 - 260
      Abstract: This research intends to explore the influential factors which constitute the successful new product development (NPD) in Japan and China. In order to investigate it, the new product development scorecard (NPDSC) has been utilised as a self-evaluation tool for participated companies in these countries. There are 454 data samples from Japan and 99 from China. The scores in each assessment area are compared between Japan and China. The result shows that Japanese NPD performance level is better than Chinese. Subsequently, factor analysis has been conducted by using the result of NPDSC in order to identify the significant factors which establish the operational performance of NPD in each country. The result of factor analysis indicates that the NPD structures in Japan and China are considered differently. Finally, correlation analysis has been conducted between extracted factors and financial bottom, which indicates that improving NPD performances brought a positive impact on financial outcomes.

  • Inventory distribution problem via stochastic programming
    • Authors: Takayuki Shiina, Masayuki Umeda, Jun Imaizumi, Susumu Morito, Chunhui Xu
      Pages: 261 - 277
      Abstract: Previous research on inventory distributions between local warehouses or retailers (bases) has focused separately on either of two types of stock transshipment policies: preventive lateral transshipments or emergency lateral transshipments. Each of these has its advantages and disadvantages, and combining these policies may well enable merchandisers to achieve higher service levels. Thus, the combined use of these policies is the focus of the present study. A stochastic programming problem is formulated with demand as a stochastic variable, and the policy of using both preventive and emergency lateral transshipment is examined for its effectiveness while solution methods are examined for their efficiency.
      Keywords: stochastic programming; L-shaped method; inventory distribution; stock transshipment

  • Evaluating and selecting hospital locations using fuzzy multicriteria
           decision making
    • Authors: Takayuki Shiina, Masayuki Umeda, Jun Imaizumi, Susumu Morito, Chunhui Xu
      Pages: 278 - 291
      Abstract: The hospital location evaluation and selection process is complex and challenging owing to the multi-dimensional nature of the process and the presence of uncertainty and imprecision inherent in the decision making process. To ensure effective decisions are made, this paper presents a new approach for evaluating and selecting hospital locations. The evaluation problem is formulated as a multicriteria decision making problem, and a fuzzy multicriteria decision making algorithm is developed for evaluating and selecting hospital location alternatives. Linguistic terms approximated by fuzzy numbers are used to represent the subjective assessments of the decision maker. To avoid the complex and unreliable process of comparing fuzzy numbers usually required in fuzzy multicriteria decision making, a new algorithm is developed based on the concept of ideal solutions. A hospital location selection problem is presented to demonstrate the effectiveness of the approach.

  • A 3D plant layout model considering pipeline route arrangement
    • Authors: Shunichi Ohmori, Yuki Nono, Kazuho Yoshimoto
      Pages: 292 - 307
      Abstract: We have developed a three-dimensional plant layout model considering I/O points and pipeline route arrangement. It is known that the much of operating costs in a typical industrial plant can be attributed to layout and pipeline design, and thus, the computer-aided layout has been studied to help layout planners consider various alternatives in a very short time. In this paper, we proposed a two-phase method: layout arrangement and pipeline arrangement. In the layout arrangement, we use continuous representation model for simplicity and accuracy, using MIP-based formulation. We apply particle swarm optimisation (PSO) to get a preferred set of relative-positioning of equipments quickly. We then optimise the layout arrangement under the specified relative-positioning. In the pipeline arrangement, we cast the plant layout into the graph representation. To cast layout representation, we propose graph creation technique called '3D min-max method' that enables us to project nodes and arcs onto the obtained layout. We then set the pipeline route onto the shortest path between equipment, using Dijkstra's method. In the numerical experiments, we show how our method can be applied to industrial application.
