When emergency occurs, a reasonable and efficient resource scheduling system is urgently needed to deal with influences caused by emergency. In regard to the scheduling problem of single one-time consumption resources in the emergency logistics system, this paper establishes a resource response decision model with the goal of minimum emergency response time, least saving points, highest reliability...
Planning and Scheduling is a decision-making process of allocating limited resources to tasks over time with the goal of optimizing a certain objective. Most of them do not have a polynomial time algorithm and are NP-hard problems. The requirements from a real world application might be that several goals need to be achieved simultaneously, which makes problems even much harder to solve. This paper...
The market competition under globalization promotes enterprises to integrate resources all over the world, and the decision-making of outsourcing is becoming an important influencing factor of project scheduling. Taking subproject TCP/C1-3-1A-1 of Three Gorges Project for example, this paper constructs module network by design structure matrix, and chooses outsourcing module primarily by two levels,...
This paper proposes a novel approach in tackling the resource brokering problem in heterogeneous distributed computing systems. To obtain the best utilization of the systems, researchers are often focusing on improving scheduling algorithms and strategies with the knowledge of tasks and resources at the scheduling time. Unlike these approaches, we apply an intelligence decision making mechanism to...
It is well known that construction project management involves such objectives as duration, cost, quality, resource leveling and so on. It is necessary to integrate and balance multiple objectives in management process. So this paper firstly analyzes single-objective optimization models such as duration-cost model, duration-quality model and resource leveling model and the relationship between duration,...

According to the characteristics of the multi-resource, multi-depot and multi-objective emergency scheduling problem, this paper establishes a multi-objective mathematical model with the goal of the shortest time and the smallest cost. We propose an algorithm for multi-objective fuzzy decision using the fuzzy ideal point method, which transforms the multi-objective decision into the single-objective...
This paper provides a tutorial treatment of recent stochastic network optimization techniques, including Lyapunov network optimization, backpressure, and max-weight decision making. A new technique of place holder bits that improves delay for networking problems with general costs is also presented. An example application is given for the problem of energy-aware scheduling and routing in a wireless...
Scheduling of semiconductor wafer fabrication system is identified as a complex problem, involving multiple and conflicting objectives (makespan and minimizing waiting time for instance) to satisfy. In this study, we propose an effective approach based an artificial neural network technique embedded in a multi-objective optimization loop for multi-decision scheduling problems in a semiconductor wafer...
In this paper, we optimize the bonus-penalty structure of large-scale project on flexible resource-constraint with a Stackelberg model, and propose a parameter of Optimization-Level to analyze the impact about the Hire-Index influences on the degree of the optimization. We find that the optimization of Incentive-Intensity can make the bonus-penalty structure more effective, and the client will gain...
The problem of manufacturing scheduling is crucial but difficult due to its computational demands. Many general-purpose meta-heuristics or multi-agent scheduling systems with social- or natural-inspired protocols for agent interacting or decision making have been widely adopted to provide optimal or suboptimal solutions. In this paper, more relevant rules are found from the known optimal solutions...
Scheduling and decision-making in container terminal logistics system (CTLS) has been the focus of research and application. This paper remodels the operation of CTLS through advancing an innovative multilevel control and feedback framework and methodology. That utilizes the knowledge engine which lies in business intelligence platform to drive the simulation and optimization engine indwelling in...
We study channel aware distributed scheduling in ad hoc networks where many links contend for the common channel using random access, and the focus here is on the model where each transmitter node has multiple intended receivers. In such a network, channel probing takes place in two phases: 1) in phase I, all transmitters contend for the channel using random access to reserve the channel, and the...
This paper deals with multicriteria decision-making applied to discrete-continuous scheduling problems. The need to quickly generate good compromises between conflicting objectives requires the implementation of fast multicriteria scheduling strategies based on simulation and optimization methods. The purpose of this paper is to compare the solutions of five scheduling strategies so as to select the...
Advanced planning and scheduling (APS) has been a well-known term in manufacturing being used to refer to supply chain management suites and, more specifically the forecasting, planning and scheduling applications within them. However, the applicability of that part of ERP/SCM systems has been so far limited to product-driven industries. Despite the increased importance of services, integrated APS...
Workforce scheduling, shift design and staff allocation are the major problems in call center management. The aim of the call center manager is to allocate and dynamically update the workforce so that the incoming calls are answered in the shortest possible time, above certain service level measures. The software tools developed to aid decision making in these areas use the models that are based on...
The decision of planning and scheduling for phosphor-chemical enterprise is very complex and difficult, which is a research area that needs to be studied thoroughly. In this paper, a model optimizing planning and scheduling for a phosphor-chemical enterprise is presented in consideration of the operation processes, including mining, mineral processing and chemical fertilizer producing. Also, some...
