Analysis Modeling and Simulation of a Poly-Bag Manufacturing System


The cost of raw material of poly-bags increases and fluctuates with an unpredictable trend. Further, legal restrictions imposed on some types of polythene products adversely affects for the demand.

In this context, entrepreneurs engaging in poly-bag manufacturing face major challenges. With the purview of optimizing the poly-bag manufacturing process, authors attempted to analyze, model and simulate the poly-bag manufacturing process in the light of posed challenges. This paper presents preliminary analysis, modeling and simulation strategies of a poly-bag manufacturing system. In addition, a risk prioritization method is proposed in the preliminary analysis and also a simulation tool is developed.

SWOT Analysis
The threats from external environment to the system were legal restrictions implemented for some types of poly-bag products, environmental issues, fluctuation of raw material prices, and lower prices offered by the competitors (price competition). In addition, some technical problems such as thickness controlling of films and higher machine setting time (mainly in printing section) were the other challenges faced by the poly-bag manufacturing system. The final SWOT chart developed is shown in Figure 4. The chart shows the strengths, weaknesses, opportunities, and threats and their origins.
