An ICT-based framework to improve global supply chain integration for final assembly SMES

Journal of Enterprise Information Management, Aug 15, 2018

Purpose To access new markets and improve sourcing practices small to medium sized manufacturing ... more Purpose To access new markets and improve sourcing practices small to medium sized manufacturing companies (SMEs) increasingly seek suppliers and customers in distant countries. Yet these new relationships with global partners often pose problems of an agency nature. The purpose of this paper is to directly address these challenges through the proposal of an information and communication technology (ICT)-based framework. Design/methodology/approach There has been very little research into how lead SMEs manage their global supply chains and the challenges they face. This paper uses a case study investigation to analyze how four French SMEs – final assemblers of machinery in the farming and agri-business sector – manage their international supply chains. Findings It was observed that the relationships and interactions between the SMEs and their immediate upstream and downstream partners were dominated by the agency problem and fell into six distinct categories (termed “barriers” to effective supply integration), namely; asymmetries, contractual design, supplier dependence, product specifications, supply chain complexity and performance monitoring. Originality/value The contribution of this paper is that a conceptual frame work was developed in which ICT solutions are offered to help address the barriers to supply chain integration, thus reducing the overall risk exposure due to externalities and problems of agency.

Unreliable Production Lines with Simultaneously Unbalanced Operation Time Means, Breakdown, and Repair Rates

The lines were simulated with various line lengths, buffer capacities, degrees of imbalance and patterns of MT and unreliability imbalance. Data on two performance measures, namely throughput (TR) and average buffer level (ABL) were gathered, analyzed and compared to a balanced line counterpart. A number of conclusions were made with respect to the ranking of configurations, as well as to the relationships among the independent design parameters and the dependent variables. It was found that the best configurations are a balanced line arrangement and a monotone decreasing MT order, coupled with either a decreasing or a bowl unreliability configuration, with the first generally resulting in a reduced TR and the second leading to a lower ABL than those of a balanced line.
