兼顾功能与协调的企业专利质量评价研究——中国上市芯片企业的实证分析

现有研究缺乏一个较为合理完善的针对企业层面的专利质量评价方法,为科学、合理地评价企业专利质量,从专利技术质量、法律质量和经济质量三个维度建立了企业专利质量评价体系。基于主客观组合赋权法,进一步利用客观偏好系数融合两种聚合算子构建了兼顾功能与协调的企业专利质量组合赋权评价模型。并对2010年至2015年中国上市芯片企业专利质量进行实证研究,结果表明:该时期内芯片企业专利质量整体发展情况较为良好,但部分企业评价值存在较大起伏;一些芯片企业存在专利质量指标间“不协调”的问题,可能造成评价结果“虚高”,这在规模较小的企业中更为普遍;发明专利在芯片企业专利质量中具有重要地位。本文的研究可对企业提升专利质量以及政府制定专利政策提供实践借鉴。

Does knowledge management matter? Assessing the performance of electricity distribution districts based on slacks-based data envelopment analysis

This study uses slacks-based data envelopment analysis (DEA) to examine the performance of electricity distribution districts (EDDs) in Taiwan in 2004. It also explores the relationship between a knowledge management system (KMS) and variations in the efficiency of EDDs in the Taiwan Power Company from 2000 to 2004. The findings show that the EDDs performed well in terms of managerial efficiency in 2004, and 75% of the districts exhibited an increasing performance variation when using cross-period analysis for that period. We show that there is a positive relationship between a KMS and variations in organizational efficiency. In addition, we present a decision-making matrix and conceptual map to help EDD managers improve their managerial efficiency and skills. This study contributes to the field of knowledge management research by applying the DEA model to link the performance between KMS and an organization. Several significant findings emerge from the study.     

A single-stage supply chain system controlled by kanban under just-in-time philosophy

The production system using kanban was pioneered by Toyota Motor Company in Japan and subsequently it was adopted by numerous other Japanese and US companies for applying the just-in-time manufacturing principles. This research studies a single-stage supply chain system that is controlled by kanban mechanism. The supply chain system is modelled as a mixed-integer nonlinear programming (MINLP) problem. It is solved optimally by branch-and-bound method to determine the number of kanbans, batch size, number of batches, and the total quantity over one period. Meanwhile, the kanban operation between two adjacent plants is worked out considering the factors of loading and unloading time, and transport time. Coupled with plant-wide efforts for cost control and management commitment to enhance other measures of performance, a logistics system for controlling the production as well as the supply chain system is developed, which results in minimizing the total cost of the supply chain system. The results show that the improvements in reduction of inventory, wasted labour, and customer service in a supply chain are accomplished through the kanban mechanism.

Effects of product postponement on the distribution network: a case study

This case study is based on a supply network analysis conducted at 3M Company, a large multi-national company headquartered in Maplewood, Minnesota. The company has developed product colouring technology that enables product postponement. This study focuses on the development of a discrete-event simulation model and inventory management equations to accurately portray the behaviour of the proposed distribution network that supports product postponement capability. The paper describes, in detail, the modelling process in the context of this actual case study. In this study, it is shown that properly devised product postponement strategy allows for best-in-class delivery within a specified lead-time. The reasons for choosing this inventory management practice are discussed. The benefits and drawbacks of product postponement are reviewed in general terms. Simulation as a tool for analysing supply networks is developed and evaluated for its ability to support a data-driven decision process.     

Nash bargaining and leader–follower models in water allocation: Application to the Zarrinehrud River basin,Iran

Mathematical models for conflict resolution are very important in integrated water resources and environmental management. This study proposes a new methodology to resolve conflicts among different water users and water suppliers while considering environmental requirements and the system’s constraints. A two-level leader–follower model is applied to maximize the net benefit with the Iran Water Resources Management Company as the leader and agricultural, domestic, and industrial users as followers subject to the system’s constraints. As a comparison, the Nash bargaining solution is also used to find a solution when simultaneous moves are assumed by the participants. The suggested method is then applied to the real case of the Zarrinehrud River basin that is one of the areas facing water shortages in Iran. For the actual optimization, Genetic Algorithm is used in order to avoid local optimum. As the contribution of this study, the results show that benefits for the leader in the leader–follower model increased in comparison with the Nash bargaining solutions.
