Abstract: Enhancing the productivity of the garment manufacturing SMEs is mandatory in order to make the garment manufacturing SMEs competitive. Unfortunately; it still has a domain of low productivity. This study is aimed to identify the factors that influence productivity in correspond to increase the productivity of garment manufacturing SMEs. The general objective of this research is to develop a productivity improvement method that supports garment manufacturing small and medium enterprises (SMEs) to enhance their productivity by identifying the possible productivity factors and selecting the intervention areas. To achieve this objective, a literature survey has been conducted to get empirical knowledge. The existing productivity measurement and improvement practices, and productivity factors of the garment SMEs have been assessed. Primary and secondary data were collected from garment manufacturing SMEs by using a well-structured questionnaire, interviews and personal observation at the manufacturing site. From the thesis working capital, business network, sourcing, supply chain responsiveness, supply of raw material, wage/minimum wage, working condition, product quality, technology, health and safety, production efficiency, motivation, business regulation and restriction are productivity factors identified that affect garment manufacturing SMEs productivity. Since, all the productivity factors identified do not have equal impact on productivity of the garment manufacturing SMEs. In addition, the resources are limited to solve all the problems associated with productivity factor. Therefore, deciding the intervention areas which are potential for productivity improvement is very important. The intervention areas identified are related human, capital, material and process. This requires organized and sustainable productivity improvement method to solve the problems associated with productivity. Therefore, a PIM based on this requirement has been developed. This research concludes by proposing a conceptual frame work for productivity improvement of the garment SMEs along with the implementation steps for the frame work.

Abstract: In order to improve the finishing performance of the magnetic abrasive finishing combined with electrolytic (EMAF) process for finishing SUS 304 stainless steel, the finishing characteristics are further studied in this paper. Firstly, the processing characteristics of electrolytic process compounded in EMAF process is investigated more detailed. In the early stage of electrolytic processing, the processing time is subdivided into three stages, each stage is 24 s. It was found that during the processing, the value of surface roughness will be an upward trend in the early stages of processing, and then turn to a downward trend. Then based on the experimental results of electrolytic processing, the optimal time of EMAF processing is discussed. In this part, the ratio of EMAF processing time and MAF processing time within 10 min is explored, and it is found 2 min of EMAF processing and 8 min of MAF processing can obtain better surface roughness. Finally, the MAF processing and EMAF processing under the same experimental conditions are compared, and the experimental result shows that finishing efficiency of EMAF process is higher than that of MAF process. In this study, the best combination of processing time is 2 min EMAF processing + 8 min MAF processing, the processing voltage is 6V, and the concentration of NaNO3 aqueous solution is 20%.

Abstract: Kanban is credited as a major means to controlling the inventory within a manufacturing system. Determining the optimum number of Kanban is of great interest for manufacturing industries. To fulfill this aim, an integrated modelling approach using discrete-event simulation technique and Kanban Lean tool is developed for a pull system ensuring an optimum Kanban number. This research has developed a base-case simulation model which was statistically validated using ANOVA. Initial Kanban number obtained from the mathematical model of Toyota motor company is used to obtain initial results. A Kanban integrated simulation model is developed that employed the idea of pull system that required the arrival of a customer for a product and Kanban pair to proceed through the production steps. The Kanban-Simulation integrated model is further used to test the effect of different Kanban numbers to obtain the best value of Kanban which is selected as 275. This approach has been applied on a case company involved in the manufacturing of agricultural and construction metal hand tools. The optimum Kanban number is selected by simulating the model about three performance indicators: customer waiting time, weekly throughput, and Work-in-progress. The analysis of the results obtained from the proposed integrated Kanban-simulation model showed a 76.7% reduction in the inventory level. The integrated Kanban-simulation model has also given a minimum customer waiting time of 0.84 Hrs. and a maximum throughput value of 737 Pcs of shovels. The integrated Kanban-simulation model is useful for manufacturing industries working to avoid overproduction waste and greatly reduce inventory costs.

Abstract: The construction industry has been grappling with what waste material can substitute for sand in producing quality hollow concrete blocks. This gap motivated the researchers to conduct this study, which aimed to investigate the rigidity of concrete blocks using sawdust as a substitute for sand. The study was designed to test the compressive strength of developed hollow concrete blocks and compare it with the acceptable standard set by the Department of Public Works and Highways in the Philippines. The researchers obtained the results through a thorough observation from the 28-day curing process and compressive strength value using the Department of Public Works and Highways compressive strength machine. Mean and compressive strength formula (F=P/A) was used to analyze the result of the sampled hollow concrete blocks. Based on the forenamed findings, the researchers observed that the compressive strength and the mass of concrete samples decrease as sawdust increases. However, these data are insufficient to conclude that the concrete samples achieved the properties of a durable and robust concrete block. Thus, the researchers profoundly suggest increasing the number of samples to validate the findings. Moreover, other tools that can be used to analyze the rigidity of developed hollow concrete blocks using sawdust as a substitute for sand are also recommended.
