Abstract
In the competitive market of apparel manufacturing, lead time for production plays a significant role in the delivery of the produces impacting the entire supply chain. Nowadays, composite manufacturers are leaning towards delivering within the shortest possible time to retain customers in this competitive market. To meet this challenge, proper production planning either using the correct method or the appropriate tools is a prerequisite condition; otherwise, mills will inevitably suffer losses or fail to drain out the maximum possible profit from the produces and may also suffer from promoting more expenses rather than yielding revenues. This study deals with the development of a linear programming model in order to reduce the complexity of the scheduling problem of a Composite Textile Industry in pursuit of maximizing profit or minimizing production costs. The model is developed considering process segmentation, utilization of machines and other resources, with respect to lead time. Four different components of the lead time are derived and an excel solver is used in solving the model.

We mainly focus on Manufacturing Lead Time (MLT)
Summary
Production planning and control (PPC) plays a vital role in the RMG (Ready-made Garments) manufacturing industry. More effort put on planning stages can ensure profit maximization through waste reduction, lead time reduction, maximum utilization of current resources. Planning the monitoring activities to ensure that proper control measures are in place and the desired product is achieved with respect to quantity, quality, delivery schedule, and cost of manufacturing to meet the customer requirements within the specified time frame. A knitting factory has many processes involved with the product such as knitting, dyeing, washing, all-over print, yarn dyeing, embroidery & sewing Between these processes, we must follow several ladders which help us to attain the knitted garments to the customer with the ensuring quality. We must consider all the constraints for it and a linear model is developed considering all these constraints to maximize profit through the optimization of lead time for different processes
