Determined the reorder interval for the warehouse and the retailers using Production Control Concepts

Implemented the theoretical concepts in MS Excel Solver to find out the optimum reorder interval

Verified 6% cost reduction using optimum policy in comparison with Power of Two policy

1) Supply chain network model was developed to locate the different factories and warehouses using IBM ILOG

2) Conducted "What-If" scenarios to obtain the optimum setting of number of facilities for the Supply Chain Network and selected the network with the lowest cost

3) Represented the network on a geographical interface

Worked in a team of three people to modify existing facility to accommodate the business growth.

Increased pick locations by 66% by the end of the planning horizon

Calculated the capital expenditure for the retrofit over a five year planning horizon and ensured the design within the allocated budget

Proposed a future building drawing to accommodate the changes

1) Prepare and explore data to identify patterns in the data and perform Descriptive Analysis.
2) Developed predictive models using different techniques like Regression, Decision Trees, Neural Networks
3) Used SQL queries to merge the data sets and analyzed data in MS Excel
4) Carried out RFM Analysis, clustered and segmented customers to score and predict future revenues using SAS Enterprise Miner

• Formulated and coded Transportation Algorithm as a Min Cost Network Flow problem SAS/OR, and observed the computation time for different simplex methods

• Evaluated the optimal values of the objective and minimized the total error using L-1 (linear) regression

• Performed RFM analysis and Segmented customers based on their purchase history using different clustering algorithms
• Analyzed buying patterns of customers by different channels
• Built models to predict future revenues for the company

Created the back-end database application called Presentation Central (PreCent) for the online conference abstract submission, using Microsoft Access and System Architect.

Developed Use Cases, Interaction diagrams and Data flow diagrams using Petri nets and IDEF notations to facilitate Access Implementation using System Architect.

Developed a manual for the End user and implemented the application.

Performed in depth analysis of buy and build opportunities for a cartridge company based on production planning, inventory turnover ratio using MS Excel

Evaluated both the opportunities by forecasting the Income Statement and Balance Sheet using Crystal Ball and OptQuest
