Abstract :
Purpose: The purpose of this paper is to propose a grey clustering evaluation model based on analytic hierarchy process (AHP) and interval grey number (IGN) to solve the clustering evaluation problem with IGNs. Design/methodology/approach: First, the centre-point triangular whitenisation weight function with real numbers is built, and then by using interval mean function, the whitenisation weight function is extended to IGNs. The weights of evaluation indexes are determined by AHP. Finally, this model is used to evaluate the flight safety of a Chinese airline. The results indicate that the model is effective and reasonable. Findings: When IGN meets certain conditions, the centre-point triangular whitenisation weight function based on IGN is not multiple-cross and it is normative. It provides a certain standard and basis for obtaining the effective evaluation indexes and determining the scientific evaluation of the grey class. Originality/value: The traditional grey clustering model is extended to the field of IGN. It can make full use of all the information of the IGN, so the result of the evaluation is more objective and reasonable, which provides supports for solving practical problems. © 2019, Emerald Publishing Limited.

Abstract :
Purpose: Flexible job-shop scheduling is significant for different manufacturing industries nowadays. Moreover, consideration of transportation time during scheduling makes it more practical and useful. The purpose of this paper is to investigate multi-objective flexible job-shop scheduling problem (MOFJSP) considering transportation time. Design/methodology/approach: A hybrid genetic algorithm (GA) approach is integrated with simulated annealing to solve the MOFJSP considering transportation time, and an external elitism memory library is employed as a knowledge library to direct GA search into the region of better performance. Findings: The performance of the proposed algorithm is tested on different MOFJSP taken from literature. Experimental results show that proposed algorithm performs better than the original GA in terms of quality of solution and distribution of the solution, especially when the number of jobs and the flexibility of the machine increase. Originality/value: Most of existing studies have not considered the transportation time during scheduling of jobs. The transportation time is significantly desired to be included in the FJSP when the time of transportation of jobs has significant impact on the completion time of jobs. Meanwhile, GA is one of primary algorithms extensively used to address MOFJSP in literature. However, to solve the MOFJSP, the original GA has a possibility to get a premature convergence and it has a slow convergence speed. To overcome these problems, a new hybrid GA is developed in this paper. © 2019, Emerald Publishing Limited.

Abstract :
Genetic algorithm is one of primary algorithms extensively used to address the multi-objective flexible job-shop scheduling problem. However, genetic algorithm converges at a relatively slow speed. By hybridizing genetic algorithm with particle swarm optimization, this article proposes a teaching-and-learning-based hybrid genetic-particle swarm optimization algorithm to address multi-objective flexible job-shop scheduling problem. The proposed algorithm comprises three modules: genetic algorithm, bi-memory learning, and particle swarm optimization. A learning mechanism is incorporated into genetic algorithm, and therefore, during the process of evolution, the offspring in genetic algorithm can learn the characteristics of elite chromosomes from the bi-memory learning. For solving multi-objective flexible job-shop scheduling problem, this study proposes a discrete particle swarm optimization algorithm. The population is partitioned into two subpopulations for genetic algorithm module and particle swarm optimization module. These two algorithms simultaneously search for solutions in their own subpopulations and exchange the information between these two subpopulations, such that both algorithms can complement each other with advantages. The proposed algorithm is evaluated on some instances, and experimental results demonstrate that the proposed algorithm is an effective method for multi-objective flexible job-shop scheduling problem.

Abstract :
Selection of reverse logistics service providers is a typical multiple attributes decision-making problem. We establish an evaluation index system for the reverse logistics service provider selection and propose a new multiple attributes decision-making method, GI-TOPSIS, based on combinational weight determination. In terms of weight determination, we combine ANP with entropy method to consider the dependency of evaluation indices and the information of evaluation data. Furthermore, we introduce the degree of grey incidence into TOPSIS and use relative similarity degree to reflect the distance differences and shape changes, which is more complete and clear. Finally, an empirical study on the reverse logistics service provider selection in an electronic,manufacturing enterprise is conducted, and the results demonstrate the feasibility and validity of the evaluation index system and the decision-making method.

Abstract :
Service-oriented manufacturing is an advanced manufacturing mode focused on integrating service with manufacturing. The remarkable importance is known to be strongly associated with the development of service-oriented economy in the period in which China transfers the traditional equipment manufacturing industry to the service-oriented manufacturing. We take a close insight into basic theories of service-oriented manufacturing, and then we analyze the characteristics, profiles, as well as the present situation of the equipment manufacturing. Finally, we propose some countermeasures for transferring the equipment manufacturing to the service-oriented manufacturing from the views of the aggregation mechanism, the network of innovative mechanism and manufacturing value-added chain.
