Abstract:
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.
