Modelling Supply Chain Management Processes in Engineer-to-Order Companies

ABSTRACT This paper describes the characteristics, competitive factors and supply chain management issues of an engineer-to-order company engaged in the supply of capital goods. Structured Systems Analysis and Design Methodology is used for modelling the internal processes of organisation, as well as interactions with customers and suppliers. Supply chain management decisions are clearly differentiated between tendering and contract execution. The case study demonstrates a requirement to integrate these supply chain management processes. The management of knowledge throughout the supply chain was identified as critical to achieving competitive advantage.

Leadership and transformational change in healthcare organisations: A qualitative analysis of the North East Transformation System

The research project ‘An Evaluation of Transformational Change in NHS North East’ examines the progress and success of National Health Service (NHS) organisations in north east England in implementing and embedding the North East Transformation System (NETS), a region-wide programme to improve healthcare quality and safety, and to reduce waste, using a combination of Vision, Compact, and Lean-based Method. This paper concentrates on findings concerning the role of leadership in enabling tranformational change, based on semi-structured interviews with a mix of senior NHS managers and quality improvement staff in 14 study sites. Most interviewees felt that implementing the NETS requires committed, stable leadership, attention to team-building across disciplines and leadership development at many levels. We conclude that without senior leader commitment to continuous improvement over a long time scale and serious efforts to distribute leadership tasks to all levels, healthcare organisations are less likely to achieve positive changes in managerial-clinical relations, sustainable improvements to organisational culture and, ultimately, the region-wide step change in quality, safety and efficiency that the NETS was designed to deliver.

New development: First steps towards an evaluation of the North East Transformation System

The North East Transformation System (NETS) is a programme that aims to engage the elements of NHS North East in a common vision, reshape the clinician/employer compact, and use Lean methodology to redesign work processes. After initial implementation in pathfinder sites, NETS is now to encompass other trusts in the region.

Modifying Regeneration Mutation and Hybridising Clonal Selection for Evolutionary Algorithms Based Timetabling Tool

This paper outlines the development of a new evolutionary algorithms based timetabling (EAT) tool for solving course scheduling problems that include a genetic algorithm (GA) and a memetic algorithm (MA). Reproduction processes may generate infeasible solutions. Previous research has used repair processes that have been applied after a population of chromosomes has been generated. This research developed a new approach which (i) modified the genetic operators to prevent the creation of infeasible solutions before chromosomes were added to the population; (ii) included the clonal selection algorithm (CSA); and the elitist strategy (ES) to improve the quality of the solutions produced. This approach was adopted by both the GA and MA within the EAT. The MA was further modified to include hill climbing local search. The EAT program was tested using 14 benchmark timetabling problems from the literature using a sequential experimental design, which included a fractional factorial screening experiment. Experiments were conducted to (i) test the performance of the proposed modified algorithms; (ii) identify which factors and interactions were statistically significant; (iii) identify appropriate parameters for the GA and MA; and (iv) compare the performance of the various hybrid algorithms. The genetic algorithm with modified genetic operators produced an average improvement of over 50%.
