数字技术应用情境下如何提升企业创新效应? 协同自发抑或协同响应

数字技术能够对组织协同创新活动以及数字经营环境产生差异化影响,重塑企业创新效应形成机制与实践路径。因此,深入探究数字技术与组织、环境间的联动交互及组态匹配关系对特质各异的企业协同创新路径研究具有重要意义。基于协同视角构建数字技术应用情境下的TOE分析框架,通过对64家数字密集型企业进行模糊集定性比较分析,结果表明：组织与数字技术在多主体协同过程中的交互方式主要分为协同自发与协同响应,具体包含4种组态类型。协同自发方式主要包括以高层次人才为主导的人才驱动型与以组织开放度为主导的文化引领型;协同响应方式主要包括以地区经济发展水平为主导的需求推动型与以政府注意力分配为主导的政策拉动型。结论能够为解释企业创新应用数字技术提供新的理论视角,为不同技术条件与资源禀赋的企业提供针对性协同策略,为我国协同创新实践提供新的优化路径,为推动数字经济高质量发展提供新的指导方向。     

A review of the extensions of a modified EOQ model for imperfect quality items

Imperfect items in the raw material and production stages of a supply chain directly impact the coordination of the product flow within a supply chain. In response to this concern, production and inventory lot sizing models, which incorporate imperfect items into their formulation have become an important and growing area of research. The contribution of Salameh and Jaber (2000) is one of the fundamental models on lot sizing when procured items are of imperfect quality. Over the past decade, there has been a noticeable amount of interest in the EOQ model for imperfect items that was set forth in Salameh and Jaber (2000). Several researchers have published adaptations and extensions of this original model that address supply chain coordination, quality improvement and yield management, and the impact of human error on production and inventory systems. In this paper, we summarize the current body of research that has extended the Salameh and Jaber (2000) EOQ model for imperfect items. Some possible future research directions are identified at the end of the paper.     

Fuzzy logic in manufacturing: A review of literature and a specialized application

Manufacturing decisions inherently face uncertainties and imprecision. Fuzzy logic, and tools based on fuzzy logic, allow for the inclusion of uncertainties and imperfect information in decision making models, making them well suited for manufacturing decisions. In this study, we first review the progression in the use of fuzzy tools in tackling different manufacturing issues during the past two decades. We then apply fuzzy linear programming to a less emphasized, but important issue in manufacturing, namely that of product mix prioritization. The proposed algorithm, based on linear programming with fuzzy constraints and integer variables, provides several advantages to existing algorithm as it carries increased ease in understanding, in use, and provides flexibility in its application.

Dynamic management of aircraft stand allocation

This paper aimed to present an original approach for solving the aircraft stand allocation (SA) problem dynamically when due to operational disturbances, the planned allocation cannot be accomplished. The proposed Multiple-criteria Dynamic Stand Allocation (MDSA) method uses fuzzy logic to support decision-making under uncertainty. The MDSA method provides effective solutions in a short time, necessary for traffic management in case of delays, emergency, and untypical cases. It considers partially conflicting points of view of different airport users (airport managers, air traffic controllers, airlines, handling agents, and passengers) and may significantly support managers on the SA problem. The approach proposed can also be used for creating an initial SA plan for a considerable number of aircraft.
