This paper presents a novel linear switch reluctance machine (LSRM) with segmental stator. The principle of the presented machine is given and compared to the well-known teeth type linear switch reluctance machine. Because the presented machine incorporates a simple concentric winding and concrete ferrite-magnetic segmentations, it features unique magnetic circuit compared to teeth type linear reluctance machine. It is found that the presented linear reluctance machine gains favorable superiority over the teeth type linear reluctance machine in terms of high force density, high reliability and low cost. Different topologies of the presented machine are given and both their merits and demerits are discussed.

An alternative source of heat energy to firewood called, palm waste briquette, has been developed from oil palm fruit process wastes. These wastes (sludge, shell, fibre) are compounded in a volumetric ratio of 1:2:3 and moulded into briquettes. The performance evaluation of a low cost women friendly palm waste briquette moulding machine was carried out. The evaluation showed that the machine designed and fabricated using readily available low carbon steel (mild steel) and employing the vertical screw thread mechanism in its operation, produces three different sizes of briquette (industrial sizes, medium sizes and domestic sizes). It requires only two unskilled operators and has a daily throughput of about 1,300kg briquettes (i.e. 400 pieces-industrial size or 800 pieces-medium size or 1,600 pieces-domestic size) unlike a modified brick moulding machine which has a daily throughput of 120 pieces industrial size

PurposeThis study aims to create a reliable, collaborative and sustainable business environment with suppliers of a company for providing high-quality and low-cost products on time. A supplier management system that sustains existing suppliers by sharing work based on systematic performance evaluation while developing the supplier base with potential suppliers is proposed.Design/methodology/approachBuilt on quantitative approaches, supplier management functions are integrated in the designed system. A quantitative strengths, weaknesses, opportunities and threats (SWOT) analysis is adapted for evaluating potential suppliers. A multi-objective integer linear programming (ILP) model is developed for the distribution of orders among selected potential and existing suppliers. A performance evaluation scheme based on an exponentially weighted moving average (EWMA) is proposed to evaluate and monitor suppliers' performance over time.FindingsProposed system develops a supplier base by methodically selecting and approving new suppliers, and a sustainable relationship with both new and existing suppliers is established based on performance over time. Decisions on retaining or removing suppliers from the base are objectively made by quantitative evaluations. Orders are fairly distributed among suppliers under the constraints imposed by the management. Dependence on a certain set of suppliers and its associated risks are reduced while agility in offering goods is enabled.Originality/valueBusiness processes for selecting new suppliers, distributing orders among all suppliers, evaluating and monitoring performance over time are quantitatively integrated to add value in operational decision-making. The proposed system is original in the holistic approach for managing and sustaining multiple suppliers of a company based on performance.
