A NOTE ON HOLDING COSTS AND LOT-SIZE ERRORS

This note examines the sensitivity of the basic economic-order-quantity inventory model to lot-size errors when holding costs are assumed to be a strictly increasing (though not necessarily linear) function of average inventory. In particular, we show that the penalty associated with ordering either too much or too little is a function not only of the size of the error but of the shape of the holding-cost curve as well. We demonstrate that, under certain conditions, even relatively small lot-size errors can be extremely costly.     

Concepts,Theory, and Techniques PRINCIPLES OF MULTIOBJECTIVE OPTIMIZATION*

This paper attempts to isolate and analyze the principal ideas of multiobjective optimization. We do this without casting aspersions on single-objective optimization or championing any one multiobjective technique. We examine each fundamental idea for strengths and weaknesses and subject two—efficiency and utility—to extended consideration. Some general recommendations are made in light of this analysis. Besides the simple advice to retain single-objective optimization as a possible approach, we suggest that three broad classes of multiobjective techniques are very promising in terms of reliably, and believably, achieving a most preferred solution. These are: (1) partial generation of the efficient set, a rubric we use to unify a wide spectrum of both interactive and analytic methods; (2) explicit utility maximization, a much-overlooked approach combining multiattribute decision theory and mathematical programming; and (3) interactive implicit utility maximization, the popular class of methods introduced by Geoffrion, Dyer, and Feinberg [24] and extended significantly by others.

中国与荷兰曲棍球后备人才培养现状对比分析

曲棍球后备人才是一个国家曲棍球竞技水平的标志。荷兰是曲棍球后备人才发展较好的国家,他之所以长盛不衰,一个重要的因素在于有一个雄厚的群众基础和一个科学并行之有效的后备人才培养体系。目前中国后备人才培养方面与荷兰相比存在着问题和不足,这些对中国曲棍球项目的可持续发展是非常不利的。针对上述状况,本文提出了中国曲棍球管理部门应加强和完善管理体制,建立符合中国具体国情的曲棍球后备人才培养机制。     

A case study of the impact of integrated project governances on PPP project performance

Under the new normal state, the PPP project will play a more and more important role in the social and economic development of China. To improve the performance of PPP project management, it is necessary to implement integrated project governances. Firstly, according to the index system of two kinds of PPP projects governances (Contract Governance and Relationship Governance) and PPP project management performance determined by theoretical analysis, the DDX project is selected as the analysis object. After identifying the case, this paper explains the basic information and preliminary work of the case. Then, the three contents of contract governance, relationship governance and project performance are analyzed comprehensively. Case studies show that all of these two governance modes have positive effects on project management performance. However, due to the lack of information in the case, the validity of the conclusion also needs to be verified again.
