Modeling of a Supply Chain Network using Lorenz Model and Identification of the Uncertainties/Disturbances in Pakistani Environment with a Solution to Improve the Model

Rehan Mazhar, MS EM 1283, Abasyn University Islamabad Abstract

Ever increasing competition is forcing companies to increase their rates of innovation. The increasing rate of innovation shortens each product’s duration in the market, thereby compressing each product’s life cycle. Without proper management, increasing product turnover will increase design and manufacturing costs. More frequent product development cycles require additional product development resources. Shorter production runs inhibit a company’s ability to achieve manufacturing cost reductions by exploiting

There are various supply chain models based on their usage and applicability to the organization focusing on improving the supply chain. With the ever growing evolution of the I.T there are various models which use the power of computations.

This research paper basically revolves around following research questions:

• Discussion on various modeling techniques in Supply Chain Network in detail and present the benefits and weaknesses.

• Using the Lorenz model in Chap 6, reproduce the plots in Figures 6.2, 6.3,and 6.4. Explain the procedure adopted to simulate the model and discuss the results.. Relate its significance with the supply chain network. • Identify the uncertainties/disturbances with respect to Pakistani environment. Propose/modify the supply chain model accordingly. Provide detailed results of the proposed model to convince the management to adopt this model for the

Though, these tools helped organization to have reached the limit of improving profits in varying customer needs. On the other hand, due to individual objectives of the players in the SCN, differences in the business environments and market requirements, the SCN should be modeled to meet the specific global goal of the SCN. Modeling can assist in the design and implementation of a new supply chain and efficiently managing the already existing supply chain.

There are a variety of supply chain models, which address both the upstream and downstream elements of supply chain management (SCM). Whereas, there is a need to rightly identify the Problem , effect of environmental analysis, correct variable identification, correct model selection and use of multiple model techniques based on the complexities or dynamics of SCN model.

The first categories deal with the modeling frameworks from the standard organizations or the group of companies. These are mainly targeted for the strategic decision makers.. The other category involves the simulation models of different types. These simulation models can be again classified into several categories as shown in
