Heuristics that explore specific characteristics of the problem are essential to find good solutions in limited computational time for many practical systems. This paper first presents a constructive heuristic, namely improved standard deviation heuristic (ISDH), by combining the standard deviation heuristic (SDH) with the procedure of effective double-job-insert-operator. Then, a composite heuristic,...
This paper presents a novel grouping harmony search algorithm for solving the no-wait flow shop scheduling problems with total flow time criteria. Flow-shop scheduling problem (FSSP) is a typical NP-hard combinational optimization. Firstly, the HS optimization mechanism and FSSP is presented and the total flow time is calculated by a novel method. Secondly, a largest-order-value rule is used to transform...
This paper proposes an effective method for the no-wait flow-shop scheduling optimization based on harmony search (HS). Flow-shop scheduling problem (FSSP) is a typical NP-hard combinational optimization. The purpose of this paper is the total flow time criterion. Firstly, the HS-based optimization mechanism and framework is presented. Secondly, the total flow time is calculated by a novel method...
Knowledge transfer scenario influences the efficiency of knowledge transfer. This paper proposes a scenario model of knowledge transfer for evaluating the efficiency of external technology and knowledge retrieval. The scenario model includes two parts. One is the relation between knowledge resource and knowledge destination, including relation scenario, management scenario, and environment scenario...
Knowledge can be acquired from organization inside and exterior. The knowledge inside organization is limited and the organization external knowledge is important to advance organization competition ability. Knowledge acquisition out of organization plays an extremely important role in organization knowledge management. This study proposed a knowledge acquisition evaluating method based on knowledge...
Direct to Agent's faithless action in a knowledge-based dynamic system, this paper presents a credit-based dynamic scheduling system, using the Contract Net Protocol as its coordination mechanism, and constructs the frame of multi-agent-based dynamic scheduling. The system acquires standardized attributes knowledge from bidding documents and knowledge of scheduling rules from experience of scheduling...
In a knowledge-based dynamic scheduling system, scheduling decision bases on historical experience knowledge, but along with the process of time and environmental change, the worm-eaten rule knowledge will affect the scheduling effect. This paper constructs a scheduling decision system based on the Contract Net Protocol. Through rough set, the system acquires scheduling rules knowledge from experience...
