Product-service system design concept development based on product and service integration

Todays business environment pressurises many high-technology companies to continuously improve the value of their products and services to remain competitive. Product-Service Systems (PSS) is an emerging paradigm that enables a tighter integration between product and service offering. The research described in this paper aims to propose a new PSS design methodology based on the integrated product and service design requirements. The process consists of three stages: the identification of design requirements, the determination of design requirements rating and the integration of product and service design requirement in order to develop a PSS design concept. A case study of mobile phones design has been chosen to validate the proposed PSS design methodology.

Performance measurement for sustainable supply chain in automotive industry: a conceptual framework

Many automobile organisations need to establish suitable measures for effective green supply chain performance measurement because they have failed in supply chain management due to their inability to develop the performance measures and metrics required for complete supply chain integration and performance measurement. This paper discusses how these challenges may be addressed through the application of a systems approach to sustainable performance measurement of automotive supply chain management. This paper briefly reviews some of papers published to evaluate and develop performance measurement of automotive supply chain as a hybrid concept.

Decision support framework for risk assessment of sustainable supply chain

Decision support systems can play a role in improving the ability of decision-makers to assess and decide as good as. We introduced new paradigm in sustainable assessment in supply chain operations. Conceptual thinking is conducted by analysing two types of thinking namely general framework of supply chain risk management and assessment of sustainable supply chain. The content of the two types of the conceptual thinking will be analysed by observing diverse perspectives such as the constituent components, structuring the components and process of adoption. We found that there are three aspects in risks of sustainable supply chain namely economics, environment and social politics aspects. Product, processes and information flow are elements that interact with each aspect as a whole system. We proposed a conceptual model of decision support for risk assessment of sustainable supply chain. It has provided functional capabilities: modelling, data management, and knowledge management to support all decision-making processes. All risk indicators are arranged in the structure hierarchical. The proposed decision support is applying non-numeric under multi decision-makers assessment. We presented a decision support framework that applicable in principle. The proposed system provided for eligibility proof to be implemented.

A framework for managing sustainable palm oil supply chain operations: a case of Indonesia

Abstract The challenges faced by the palm oil industry in Indonesia lie in the supply chain risk management, specifically in the integration of decision-making at the operational level. Problems at this level have become more apparent while the industry continues to face pressures as a consequence of the strict conditions imposed by, predominantly, international trading communities, and in some cases, by the environmental issues from domestic and overseas. As part of an effort to address the underlying problems, this paper aims to propose a conceptual framework that can be used to effectively manage the palm oil supply chain, by integrating risk assessment, performance measurement and supply chain optimisation, which will be compiled into a decision-making tool. The perceived benefits from the implementation of this framework include more realistic target planning, clearer prediction of risks and better visibility of the operating performance.

Decision Support System of Performance Assessment for Sustainable Supply Chain Management

Sustainable supply chain management (s-SCM) requires a practice tool to assess performance that able to measure, evaluate and improve the existing operations of supply chain. The research question is how to build a decision support system (DSS) for performance assessment of s-SCM. The author has designed a DSS for performance assessment of s-SCM. There are some elements in designed DSS namely existing achievement, standards, indicators achievement and priority, computation algorithm, and recommendation for improvement. Theoretical contribution of this study is the development of relationship between total and partial performance in mathematical formulation. The model that has been presented is still using generic indicators. If the particular company would like to apply model that additional indicators should change the encoding computer program. However, the modification is very easy to perform. DSS structure of this study is still able to accommodate any kind of particular requirement.

A model for vendor managed inventory by applying the economic order quantity with fuzzy demand

This paper presented a decision support model for VMI system by applying the economic order quantity (EOQ) with fuzzy demand. The model of fuzzy EOQ that has been developed in this study is intended to accommodate the fuzzy demand. Result of the study shows that the optimal quantity of fuzzy EOQ is influenced by the value of ?1 and ?2. It was known that the value of order quantity (q) will be increased if the decision-makers getting more optimistic regarding the upper limit of the sales forecast implementation. The model formulation that has been introduced fuzzy number for demand to accommodate uncertainty situation.
