In this comparative case study research, we reflect on two enterprise resource planning (ERP) implementation stories at two large petrochemical companies in China. These companies implemented the same ERP system in a similar time span (though not at the same time). They are two very large Chinese State-Owned Enterprises (SOEs) and in this paper we highlight the centralization versus decentraliz...

in this paper, the competition between two supply chains and their elements is studied. each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...

Cost efficiency measures the cost of resource by output production. While conventional cost efficiency models set targets separately for each DMU, There are cases where the Central decision making is seeking the above targets, and at the same tries to obtain the target of Min cost efficiency for the total consumption. in this paper we consider that there is a centralized decision maker (DM). In...

In this paper we consider the controller synthesis problem for multi-agent systems that consist of a set of controlled and uncontrolled agents. Controlled agents may need to cooperate with each other and react to the actions of uncontrolled agents in order to fulfill their objectives. Besides, the controlled agents may be imperfect, i.e., only partially observe their environment, for example du...

Resource scheduling problems with incomplete information and environment changes have been studied for decades. The vast majority of the research efforts in the scheduling problems under uncertainty assume a central authority with a global objective of maximizing the resource usage. In real-life scheduling problems, in addition to the dynamic environment, sometimes conflicting interests of diff...

Most current schemes for multicast routing assume that multicast routers participate both in forwarding mul-ticast packets and in control algorithms for routing, resource reservation, and group management. By separating data and control ow, and by centralizing control in distinct control elements, we have designed a simple and scalable approach to IP multicast that we call Centralized Multicast...

This article describes an investigation of local motion planning, or collision avoidance, for a set of decisionmaking agents navigating in 3D space. The method is applicable to agents which are heterogeneous in size, dynamics and aggressiveness. It builds on the concept of velocity obstacles (VO),which characterizes the set of trajectories that lead to a collision between interacting agents. Mo...

We identify a new class of algorithms for multi-robot problems called “Any-Com” and present the first algorithm belonging to that class “Any-Com intermediate solution sharing” (or Any-Com ISS) for multi-robot path planning. AnyCom algorithms find a suboptimal solution quickly and then refine that solution subject to communication constraints. This is analogous to the “Any-Time” framework, in wh...

operations centers (MOC), in which multiple DMs with partial information and partial control over assets are involved in the development of operational level plans. The MOC emphasizes standardized processes and methods, centralized assessment and guidance, networked distributed planning capabilities, and decentralized execution for assessing, planning and executing missions across a range of mi...

Supply chain management (SCM) can be defined as the systemic, strategic coordination of the traditional business functions and the tactics across these business functions within a particular company and across businesses within the supply chain (SC), for the purposes of improving the long term performance of the individual companies and the SC as a whole (Mentzer et al. 2001). One important way...
