These articles have been peer-reviewed and accepted for publication in AJMSA, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Evolution and interaction in a business model: The case of inkjet printers in Japan   Order a copy of this article
    by Yoshihiro Ito 
    Abstract: The purpose of this paper was to shed light on the process through which the business model of a certain industry evolves due to interaction caused mainly by competition among companies. To this end, I conducted a detailed investigation and analysis based on interviews with representatives of companies in the inkjet-printer business in Japan. I was able to break down the evolution of the business model into five stages, and provide details of the structure of the business model at each stage and the process through which it evolves. I performed a theoretical analysis of the logic and mechanisms of this evolution.

  • Trend of selling space layout and passing customer efficiency in recent Japanese supermarkets   Order a copy of this article
    by Masao Ohta, Yoshiyuki Higuchi 
    Abstract: Japanese companies have accumulated know-how on methods of supermarkets and are causing expansion of the supermarkets to Asia. This study aims to assess what's really going on the selling space layout in Japanese supermarkets. The layout information of newest opening and remodeling 498 stores is picked up. Most all of stores have a square shape sales floor. We focus the selling magnet concept which shows understanding the critical relationship between food products and selling spaces. We classified the layout information and divided stores into two types, standard and minority type. To understand the feature of the two types, we investigated the passing customers of the main selling zone in typical 2 type stores and show passing customer efficiency as a case study. The difference between two types is confirmed, customers are widely distributed in the standard type store, on the other hand customers are disproportionately distributed in the minority type store. This paper mentions some of their competitive advantages.rnrn

  • Analytical Methods for Perfect Partition by Set Theory   Order a copy of this article
    by Rongxin Zhan, Dongni Li, Hongbo Jin, Xiaoyu Jia 
    Abstract: A recent interesting paper was published by Yin et al. (2014). They developed a structural architecture to investigate the previous literature with three types of research problems what, why, and how. They utilized simple but rigorous set theory to define CM concepts, such as part family, machine cell, cellular manufacturing system, bottleneck machines. Then, they deduced sufficient and necessary conditions for perfectly partitioned cellular manufacturing systems. An algorithm was proposed to get perfectly partitioned manufacturing cells. The objective of this paper is to overcome the two problems in Yin et al. (2014)s research. Firstly, we modify their algorithm to get perfectly partitioned manufacturing cells. Then we extend the analysis from machine groups to a cellular manufacturing system and compare the results with the ones of Yin et al. (2014). Based on the analysis of our new model, we propose a new algorithm to generate perfectly partitioned manufacturing cells.

  • Efficient Optimization for Portfolio Selections under Prospect Theory   Order a copy of this article
    by Xiangming Xi, Chao Gong, Chunhui Xu, Shuning Wang 
    Abstract: The prospect theory (PT) is one of the most useful tools for portfolio optimization. The main concept of PT is to use a S-shaped value function to depict how human beings' mental behaviour affect their investment decisions under different risk levels. However, the complexity in the theory results in the difficulty in the proposal of efficient algorithms for global optimization. In order to make improvements, we first approximate the S-shaped value function in PT with a piecewise linear (PWL) surrogate model, and equivalently transform the resulted problem into a continuous concave piecewise linear maximization problem. Despite of the non-smoothness and non-convexity of the problem, we propose two local search algorithms based on the interior point method, and present the theoretical analysis on the convergence. Moreover, we propose a global search algorithm based on the proposed local search algorithms and the $gamma$ valid cut method in concave optimization. The numerical experiments on the historical data of different assets obtained from Yahoo concern the comparisons of the proposed algorithms and the existing methods in the literature. The results confirm the performances of the proposed algorithm on efficiency and accuracy.
