交叉学科组织发展的应然样态与多维提升——基于资源依赖视角的分析

第30届中国控制与决策会议

作者： Luhua Zhao Entong Wang Yang Li xinyu dou College of Transportation Shandong University of Science ＆ Technology

This paper aims at designing an automated exchange system for tractor and semi-trailer. The design is based on the analysis of the current exchange system and the autonomous truck system. The purpose of this design is to improve both the efficiency of exchanging and the development of drop and pull tractor. Based on the technology of sensors and information, the designed functions are realized based on two parameters reflecting errors: 1) the deviation angle between the center-line of a tractor and that of a semi-trailer;2) the distance between the upper plane of fifth wheel and the lower plane of hauling pin. The two parameters are collected and fed into a master computer which analyzes the errors and asks automated control parts to make adjustments on the errors. The automated tractor and trailer exchange system can save the effort of manual operations, automate the complex processes, and reduce the failure rate in the exchanging process. This automated system has significant improvement on the perspectives of safety and practicality. The model simulation and analysis based on SOLIDWORKS show that the system designed in this paper is feasible and has strong practical significance in safety and practicability.

交叉学科在科技发展和知识进步中扮演着举足轻重的角色,各高校纷纷建立交叉学科的实体组织,为其提供充足的发展空间和资助。通过构建资源依赖理论的分析框架对交叉学科组织发展进行分析,发现交叉学科组织在发展过程中依赖源学科、高校与社会外部组织的资源供给,呈现出积极的发展态势,但在发展过程中仍存在隐患。基于交叉学科组织的资源依赖关系对组织发展的应然样态进行分析,有利于促进组织内外通力合作,完善组织的发展运行模式与资源分配机制。未来,交叉学科组织的发展需组织内外通力合作,从创建动态调整机制、强化组织顶层设计、变革资源分配机制等多维度出发,对组织的运行机制与资源配置方式进行变革,为交叉学科组织的不断发展提供力量。
