Abstract. In order to overcome the disadvantages of Kanban Control Strategy (KCS) in non-repetitive manufacturing environments, two research approaches have been followed in the literature in past two decades. The first approach has been concerned with developing new, or ...

Supplier selection is one of the important processes in supply chain management. Regarding the emergence of sustainability issues in recent decades, companies have incorporated these issues in conventional supplier selection in order to meet governmental legislations and market demands. These issues have been noticed by various researchers. However, there are limited research activities which considered all aspects of sustainability for supplier selection problem as an integrated assessment. In this paper, an integrated approach of Fuzzy Analytical Hierarchy Process and fuzzy logic has been proposed in order to solve sustainable supplier selection problem. Fuzzy analytical hierarchy process has been used to calculate the weight of sustainable criteria and sub criteria. Then, fuzzy logic was utilized in order to assess the suppliers based on the weights acquired by Fuzzy analytical hierarchy process. Finally, a case study of petroleum industry has been carried out in order to show the validity of proposed approach.

Sustainable development is penetrating in every field of research disciplines nowadays. Procurement operation is one of the disciplines that sustainability dimensions are being incorporated into and is being established as a burgeoning field of research. Body of literature considering buyer-supplier dyad as a part of the sustainable/green procurement operation is plentiful. Given this abundant research studies, in this paper, it is aimed to conduct a systematic content analysis in order to present the state of the art in this domain via a review (appeared in international scientific journals and well-known international conferences) related to green and sustainable supplier selection and evaluation problem published between 2008 until 2014. Seven carefully designed research questions are proposed and answered based on this bibliography. Interesting results are reported in each section and gaps in the current body of literature are identified. This survey is concluded by important future directions and limitations.

This paper presents a comparison of following Production Control Strategies (PCS) Kanban Control Strategy (KCS), CONWIP, CONWIP/Pull, Basestock Control Strategy (BSCS) and Extended Kanban Control Strategies (EKCS). The PCS were examined under medium de- mand load with increasing co-ecient of variation. A Markov Decision Process (MDP) is used to model each PCS examined and these models are analysed using simulation. Detailed de- scriptions of the models of the PCS are given. The dierent strategies were compared under

ABSTRACT This paper describes a test implementation of the Core Manufacturing Simulation Data (CMSD) information model and the integration and initialisation of a simulation model in a newly developed Simulation Engine. The cost of developing, implementing and using simulation technology is high. The costs of integrating simulation models with other manufacturing applications are even higher. There is always a need to enable data exchange and sharing between simulation applications and other software applications. The idea of the CMSD effort is to facilitate the above using neutral, reusable data structures for managing actual production operations and for simulating the performance of the manufacturing system. To address the problem of time consuming pre-coding for DES projects, a knowledge extraction tool is currently being developed. The knowledge extraction tool will read data from several resources of an organisation and output it in a format that is applicable for simulation purposes. The format that we adopted follows the CMSD standard in order to describe simulation related data. In this paper we present the modelling of a complex production line of our industrial partner with the CMSD standard and the development of the translator in ManPy so that it can read the CMSD information model and run the simulation.

ABSTRACT Modern manufacturing systems are growing in scale and complexity and increasingly require integrated predictive modelling and optimisation methodologies to support routine decision making processes. The engineering of a free open source simulation modelling platform is the basis of the DREAM project, a Framework Programme 7 initiative co-funded by the European Commission. This paper reports on the capture of requirements for DREAM from four industrial end-users. These industrial end-users’ requirements and accompanying pilot cases drive the research, technology and development work in the project. The users vary in size from micro-SME to multi-national and global organisations and by industry; from semi-conductor manufacturing, medical device design and manufacture to industrial machine manufacture and pre-process/prototype manufacturers. To capture requirements from the organisations a methodology was developed which is reported on in the paper. Its outcomes provide the basis for the subsequent open-source software development. In particular, the work assessed the various partner needs in the pre-coding, simulation application development, simulation application use and data-analytics areas which cover the end-to-end usage of a simulation based decision support system.

"Recent research efforts have focused on the method of order release as an effective operations management tool. This paper examines issues relating to the selection and application of an appropriate Order Release Mechanism (ORM) for batch production flow-shops, a class of manufacturing systems in which the products are batched and flow through the system along a predefined production route. An experimental study that was conducted to investigate the application of ORMs to an existing system is described. The system configurations examined included an informal ORM practised by the company, CONWIP, a bottleneck capacity modified CONWIP policy, and Starvation Avoidance. Operating Characteristic curves were used to calculate appropriate WIP caps. Measures of performance were average WIP, average cycle time and average throughput. A ranking and selection procedure was utilised to select the best policy for each of the performance measures. CONWIP was shown to be the best policy in terms of average cycle time and average throughput achieved. This research reaffirms the findings of previous research regarding the applicability of CONWIP in batch production flow-shop systems."

Purpose
The purpose of this paper aims to evaluate field repair within product-service system (PSS) models operated by multinational manufacturers in the Egyptian emerging market to better understand the unique characteristics of this evolving market and to identify differences compared to established markets.
Design/methodology/approach
Case research was conducted on multinational manufacturers providing field repair services in Egypt. The sample is made up of 12 companies across different industries using convenience and purposive sampling. Data were collected using structured interviews.
Findings
There is no common model for field repair PSSs provision in the Egyptian emerging market even within the same industry, which is influenced by several factors. One of these factors is the market type being emerging or established. However, some commonalities have been found between some industries such as computer, telecommunications and document processing. Yet, there is no structural difference in the supply networks used to provide field repair service offerings in the Egyptian emerging market compared to established markets with the trend of outsourcing evident as a main attribute of a PSS in emerging markets. The main differences between established and emerging markets are related to country, culture and customer factors, which are market-based. Among the main challenges and risks that internationalized manufacturers face in Egypt, is the low level of customer awareness.
Research limitations/implications
Findings are limited to the studied cases and industries; yet, internationalized firms must deal with some unique challenges and difficulties in emerging markets.
Practical implications
This paper assesses PSS requirements and provides deeper insights for companies looking to provide or expand manufacturing-based offerings into the Egyptian emerging market.
Originality/value
This paper contributes to the evolving research on PSSs, particularly in emerging markets through identifying and describing different field repair PSS models in the Egyptian emerging market.
