    Design, development and implementation of management information system (MIS) of Biman aircraft maintenance for enhancing quality maintenance program
    (Department of Industrial and Production Engineering, BUET, 2005-03) Pandit, Partha Kumar; Ahamed, Dr. Mahiuddin
    E,man Bangladesh Alrlmes, the natIonal flag career of Bangladesh is now operating in domestic, regIOnal and international fOl.ltes with six DCI 0-30, four Airbus A31O-325 and four F-28 aircraft. Biman is facing tremendous crisis in flight schedlding with shortage of aircraft. Volume and cost of maintenance activities increased in the recent years due to the aging effect on DCI 0-30 and F-28 aircrali, As an international airline Biman can not compromise \~ith fl1ght safety and airworthiness as mandated by the regulatory bodies. The regulatory bodies are leAD-International Civil Aviation Orgamzation and lts local representative CAAB-Civil Aviation Authomy of Bangladesh. In the pace of global competition in airlines business, economic !light operatIOn is the key factor for existence whereas cost of maintenance is the main determinant of economlC night operation, On the other hand qualny maintenancc program is a pre-requisite for f1ight safety and airwonhiness. So to make the maintenanec more efficient and cost effective wlthollt degrading the quality of maintenance is the long felt demand of Engineenng Department ofBiman. Moreover, Biman management decided to sell its aircraft maintenanee scrvices to other airlines where a quality certificate creates some value addition in the market of aircraft maintenanec, At this moment poplilar and acceptable quality cenificate for this region is EASA (European Aviation Safety Agency)-pan 145 certificate. For becoming a EASA certified aircraft maintenance organization, Biman needs to improve in many areas ofmainten~nce- among which Reli~bility Control Program is placed in a vital position. At thls moment Biman is not in a position to implement an effecllve Reliability Control Program dlle to una,allability of proper, accurate and timely data for mamtenancc. This became the initial cause of developing a eomprehensive Management Information System suitable for aircraft maintenance ofEiman A comprehensive Management lnfonnallon System can playa vital role III providing necessary infonnation related to reliability analysis and other crucial decision making process. So it became imperative to develop a comprebensive Management lnfomlation System suitable for ~ircraft mmntenance activities ofBiman, After preliminary system analysis it was found that a LAN (Local Area 1\et\vork) based system is the most suitable one in this case. The solution needs to be user-fnendly and it should have a highly secured access control. On the basis of system analysis a LAN based system has been designed, developed and now l'e~dy for final installation. Th,s research work deals wlth different features considered in design, development and installation phases. The outcome of this work could give some directions and guideline> for quality maintenance program.

    Optimization of product mix in a knit dyeing industry
    (Department of Industrial and Production Engineering, BUET, 2004-09) Monowarul Islam, Md.; Ahamed, Dr. Mahiuddin
    Dye-house ISthe we! processmg unit in a Knit dyeing industry. There are mainly three type~ of fabric processed in dye-house (i e.- White fabric, Reactive dyed fabric and PC fabric). The processing method and processing time of these three products arc also different It is very important for dye-house to maintain an optimum ratio of these three products Consequence of non-optimal proportion of these three products (or product mix) will result in improper production planning, leading to a loss in output due to bottleneck problem in batch preparation section and finishing section. Nonoptimal product mix may lead to increase one type of product. This increased production of a particular type of fabric can delay the batch preparation and can also overload the finishing area causing shortage of fabric and shortage of trolley for loading and unloading the dyeing machInes. This in turn results in to delay in shipment Morcover, lfi order to mcet the deadlinc, sometimes the company has to send the container by air instead of sea, resulting in sIgnificant loss of money as well as good will of the company. This paper develops a linear programming model to overcome these problems. A comparison in terms of production volume between the current production planning approach and linear programming method presented.

    Study of ship breaking industry and its value chain analysis
    (Department of Industrial and Production Engineering, BUET, 2005-12) Arshad Ali Mondal, Md.; Ahamed, Dr. Mahiuddin
    Ship breaking Industry of Sitakunda in Chittagong is the main source of metal in Rangladesh. "Ibis study looks into the process of ship breaking. "lbe study v;as carried out by visiting the ship breaking yards, interviewing the managers and workers. The ~"tudyalso covered the process how materials from ship breaking is sorted and marketed. It is found from the study that the ship breaking process is quite unorganized. However the material sorting and marketing is considerably organized and efficient. The stndy found that there are rooms for improvement. The study suggested a scientific sequence of operations based on the concept of the reverse process of shipbuilding. Accordingly an organized layout is suggested for ship breaking. The study also suggested some improvement in fue marketing of ship breaking materials.
