The aim of this study is to establish an efficient distribution planning for a capacitated multi-stage supply chain. We assume that the demand information during planning horizon is given a deterministic form using a certain forecasting method. Under such a condition, we present a cost effective heuristic method for minimizing chain-wide supply chain inventory cost that is the sum of holding and backorder costs by using look-ahead technique. We cope with the capacity restriction constraints through look-ahead technique that considers not only the current demand information but also future demand information. To evaluate performance of the proposed heuristic method, we compared it with the extant research that utilizes echelon stock concept, under various supply chain settings.

Family business is the oldest and the most prevalent type of entity in the world. In India, 85% of the enterprises are owned and/or managed by families, contributing to two-third of GDP. Thus the survival of family firms, which also generates 79% of private sector employment, is of paramount importance. Effective succession planning and innovation to gain competitive edge are the two key ways to ensure family firm survival. In this paper, the interplay between family succession and innovation is qualitatively studied using case study approach. Successors and Predecessors are interviewed to gain insights in the areas of succession planning and innovation. It is observed that family succession has a positive relationship with innovation, i.e. the presence of founding family members in the ownership and/or management of the enterprise has a positive influence on innovation tendency of the family firms. The findings contribute to the family business literature on succession planning and innovation, and their inter-relationship.

Product Lifecycle Management (PLM) ranges from design concepts of products to disposal. In this paper, we focus on the production planning phase in PLM, which is related to process planning and production scheduling and so on. In this study, key decisions for the creation of production plans are defined as production-planning attributes. Production-planning attributes correlate complexly in production-planning problems. Traditionally, the production-planning problem splits sub-problems based on experiences, because of the complexity. In addition, the orders in which to solve each sub-problem are determined by priorities between sub-problems. However, such approaches make solution space over-restricted and make it difficult to find a better solution. We have proposed a representation of combinations of alternatives in production-planning attributes by using Zero-Suppressed Binary Decision Diagrams. The ZDD represents only feasible combinations of alternatives that satisfy constraints in the production planning. Moreover, we have developed a solution search method that solves production-planning problems with ZDDs. In this paper, we propose an approach for managing solution candidates by ZDDs' network for addressing larger production-planning problems. The network can be created by linkages of ZDDs that express constraints in individual sub-problems and between sub-problems. The benefit of this approach is that it represents solution space, satisfying whole constraints in the production planning. This case study shows that the validity of the proposed approach.

In the process of complex shopping mall development, all the steps (business planning step, pre-sale & completion step, management & operations step) head towards a consistent ultimate goal in an overall business perspective. In this study, we analyze using a structural equation model if an appropriate relations between each of the steps are formed to achieve the ultimate goal. In this study, we find a positive relationship between business planning step and pre-sale & completion step, and also find that for success pre-sale & completion, a faithful business plan is necessary. But we find no statistically significant relationship under significant level 0.05 among business planning step and management & operations step and the level of success, pre-sale & completion step and management & operations step and the level of success, management & operations step and the level of success. This suggests that each of the steps does not form a close relationship to achieve the consistent goal in the complex shopping mall development and each one is doing a short-sighted work for its own profit.

Proper management of small rural watershed is important since it does affect water quality improvement of larger scale watershed. Therefore, effective small watershed management guideline including participatory program of local people is required to achieve water environment improvement. Feasibility of water quality goal, short and long-term watershed management plan and funding sources were investigated by field monitoring of Hampyungchun watershed which has characteristics of rural stream, and literature review. The relevant parties and their roles fer watershed management were identified and suggested. A hybrid model, that is mixture of government driven model and NGO model, is recommended for watershed management organization in this study.

The purpose of this study was to test a causal model of employed and unemployed wives on the basis of the family resource management system theory. The data of this study were obtained from 244 wives who lived in Seoul and were financial mangers. Major findings of this study were as follows: 1. Both employed and unemployed wives, knowledge of financial management was significantly predictor of financial planning. That is, household financial mangers with more financial knowlege used more effective planning behaviors than did those financial managers with less financial konwlege. This results emphasize the significance of enhancing the financial konwledge in the household financial management. 2. For unemployed wives, expectation of household’s future financial condition was influenced by age, household income, locus of control over their financial situation, and perception of financial management’s effectiveness. The strongest predictor of expectation of the household’s future financial situation was age. Younger managers were more optimistic about the future. 3. The findings of this study support theoretical framework on the basis of the family resource management system theory, both for employed and unemployed wives.

This study developed the planning process for technical management of engineering project applying systems engineering process in order to correctly design technical management activities early during the system development projects. The developed process describes a systemic design process of a product to be developed as well as the development process and the personnel team of project organization. As an outcome of the process implemented by a Model-Based Systems Engineering(MBSE) software, a systems engineering management plan(SEMP) and a risk management plan can easily be produced.

Recently, Service Level Management(SLM) including SLA has been developing to manage the level of information systems service. Although previous SLA studies have provided the conceptual model and critical success factors, the studies have not tested the effectiveness of the SLA by way of the empirical study. In this study, we applied an innovation decision making theory to our model and tested an empirical study using of a firm survey data. We suggested a SLM model, which consists of SLA planning, application, management dimensions. We found that the SLM's management stage has an impact on performance, whereas SLM's planning and application has not. At each sub dimensional analysis, there are found that adequate SLA indicators in the application stage influences performance and change management and feedback & reporting in the management stage influence performance.
