产学研合作视角下企业技术获取协同及其与创新绩效的关系研究

企业根据自身特点选择技术合作伙伴,筛选技术来源,通过开展广泛的产学研合作实现多渠道技术获取是企业技术创新活动的重要组成部分,也是企业实现技术创新能力提升和经济效益增长的重要方式。不同技术获取模式对企业创新绩效的影响效果和作用机理差异性受到了诸多学者的重视,但企业技术获取系统是一个复合系统,很少有研究系统地分析企业技术获取系统的协同机理及其与创新绩效的互动关系。文章构建了企业技术获取系统协同发展模型,对我国企业技术获取的协同发展情况进行了实证分析,并进一步讨论了企业不同技术获取协同与不同创新绩效间的因果关系。研究表明:整体上我国企业技术获取系统处于协同演进状态,但国外技术获取子系统在发展过程中存在徘徊与波动;企业在技术获取和技术的消化吸收过程中形成了技术获取协同带动技术累计绩效和经济绩效刺激技术获取系统协同演进这两个简单的价值循联接;我国企业目前仍欠缺通过持续的技术学习实现技术累计绩效的商业化和市场化,使企业经济绩效归因于其内外部技术的研发、吸收和二次创新的能力。

Vehicle dispatching system based on Taguchi-tuned fuzzy rules

This paper presents the development of a dispatching system for a fleet of automated guided vehicles in a flexible manufacturing environment which is based on a hybrid Fuzzy–Taguchi approach. A fuzzy decision-making system emulates the human behavior necessary for multi-objective directed decision making in a dynamically evolving environment. A statistical approach based on the Taguchi method tunes the fuzzy rules to achieve near optimal performance. Simulation results demonstrate the effectiveness of this marriage of computational tools in dealing with the well-known NP-complete scheduling problem.

A comprehensive approach of planning and scheduling based on petri nets

The main results available on the use of black-and-white Petri nets for modelling, planning and scheduling manufacturing systems are presented. In the first part of the paper, the basics of Petri nets necessary to understand the subsequent presentation are introduced. Particular attention is paid to event graphs, a particular type of Petri nets used for modelling and evaluating ratio-driven systems. The second part of the paper is devoted to ratio-driven systems, their modelling and their scheduling. Job-shops, assembly systems, and KANBAN systems are used to illustrate this section. Finally, the general case is investigated of manufacturing systems subject to changing demands. An approach based on conflict-free Petri nets with input and output transitions is proposed for planning and scheduling this type of system.     

The research of ecological security evaluation for mineral-resource enterprises-a case of China

As the rapid development of economy and society in the world, the situation of ecological security has become more and more severe. The problem on ecological security is concerned with whether the continuous development of economy and society can realize or not, as well as the regional stability and international safety, so ecological security has become the primary measurement of the continuous development. Meanwhile there are a lot of research on ecological security of hometown and abroad, and the research range is becoming wider and in depth. With this background, this paper analyses the meaning of mineral-resource ecological security, sets up ecological security index system of mineral-resource enterprises based on the pressure-state-response (P-S-R) model, then determined the weights of the indices by analytical hierarchy process (AHP), and presents a method to evaluating it. After empirical analysis, the paper pointed out that evaluating the ecological environment security of mineral- resource enterprise is not only necessary but also the base of building ecological security alarming mechanism.     

Studying transition dynamics via focusing on underlying feedback interactions

The emerging need for societal transitions raises the need for a better understanding of the dynamic nature of large scale societal systems, and therefore the development of an analytical approach for drawing dynamic conclusions based on system’s dynamic mechanisms, feedback relationships and interacting components. The objective of this study is to explore the degree to which System Dynamics as an approach enhances the process of understanding transition dynamics in socio-technical systems. In other words, it is aimed to reveal the type of insights that can be developed about such systems and their dynamic behaviour using the approach, as well as the shortcomings of the approach in this challenging task. In order to do so, a modeling study aiming to understand the underlying mechanisms of the waste management transition in the Netherlands is conducted. The quantitative model developed is based on the historical case of the waste management transition of the Netherlands, and it portrays issues as the dynamics of actors’ preferences, development of infrastructure and environmental consequences of dominant mode of functioning and provides an instance for demonstrating and evaluating the feedback-focused perspective discussed in this paper. Finally, the paper discusses a set of points regarding the utilized approach, System Dynamics, observed during this study both in general and in the specific context of transitions. In short, System Dynamics stands as a promising approach mainly due to its strength in explaining the source of complex dynamics based on interacting feedback loops, but it also has certain drawbacks in the context of transitions.

A Geometric Approach to Trajectory Design for an Autonomous Underwater Vehicle: Surveying the Bulbous Bow of a Ship

In this paper, we present a control strategy design technique for an autonomous underwater vehicle based on solutions to the motion planning problem derived from differential geometric methods. The motion planning problem is motivated by the practical application of surveying the hull of a ship for implications of harbor and port security. In recent years, engineers and researchers have been collaborating on automating ship hull inspections by employing autonomous vehicles. Despite the progresses made, human intervention is still necessary at this stage. To increase the functionality of these autonomous systems, we focus on developing model-based control strategies for the survey missions around challenging regions, such as the bulbous bow region of a ship. Recent advances in differential geometry have given rise to the field of geometric control theory. This has proven to be an effective framework for control strategy design for mechanical systems, and has recently been extended to applications for underwater vehicles. Advantages of geometric control theory include the exploitation of symmetries and nonlinearities inherent to the system.     

Web based casting supplier evaluation using analytical hierarchy process

Manufacturing companies are increasingly dependent on outsourcing to improve their competitive position. At the same time, the approach to supplier selection has dramatically changed from being price-driven to one based on overall capability of the supplier, very much in evidence in the automobile castings sector facing the challenge of mass customization. In this study, 18 criteria have been identified for casting supplier assessment and segregated in four groups—product development capability, manufacturing capability, quality capability, and cost and delivery. A systematic approach to evaluating casting quality suppliers has been developed using the analytical hierarchy process, which enables the combination of tangible and intangible criteria and checking the consistency of decision-making. The approach has been implemented in a prototype web-based system.
