Developing a performance measurement system for apparel sector lean manufacturing organizations in Sri Lanka
(Sage Publications, 2013-12) Perera, P. S. T; Perera, H. S. C
Performance measurements systems were rarely adapted to changing manufacturing environments. Lean is one such practice aiming at productivity improvements. Non-cost performance improvements resulting from lean makes the inadequacy of traditional measurements for evaluating performance. Sri Lankan apparel manufacturers adapt lean manufacturing to meet global business challenges. However a study has not been done to develop an appropriate performance measurement system for lean environment in Sri Lankan apparel sector lean practicing companies. This study develops such a model from literature review and interview. Finally it is validated with the existing models.

Environmental performance evaluation in supply chain
(SAGE Publications, 2013-03) Perera, P. S. T; Perera, H. S. C; Wijesinghe, T. M
Environmental performance evaluation is an area of growing concern among the worldwide community. Consequently, measurements to evaluate environmental performance are of great importance. However, lack of a quantifiable model to study the environmental performance is a problem in this area. This study therefore attempts to quantify the environmental performance of supply chain of a manufacturing company, which requires evaluation of many criteria. Therefore, selection of environmental performance measures leads to a multi-criteria decision making problem. As a result, analytical hierarchy process is selected to develop the model and is solved with Expert Choice software. Finally the proposed model is applied to a case study company to identify the key areas of environmental performance of the company’s supply chain and to assess various product categories manufactured under those key areas.
