Regression Analysis

Introduction

Our regression analysis was done on OMNITRANS fuel consumption. This has been an ongoing issue for OMNITRANS where there seems to be an inconsistency with there CNG fuel consumption. There continues to be variance in what is consumed each day compared to the amount of miles driven. This issue is very important to OMNITRANS because it makes it very difficult to plan for future use with the CNG industry. OMNITRANS wants to have a consistency with CNG use so they can plan for budgeting purposes and new contracts that are connected with the CNG usage. We are going to establish what we believe will be a good analysis for OMNITRANS to look at and establish what is needed in order to improve there fuel consumption within the industry. This will give them an overall picture of where there is a correlation between the two factors. In our particular study it is fuel consumed and miles driven.

Data Researched

What we have done is taken 5 days worth of data points from the Fleetwatch system's reports. Fleetwatch is based for all recording purposes for all of the OMNITRANS facility. This particular report gives full details of how much fuel is consumed on each day based on filling station onsite at the OMNITRANS facility. We took every 5th days worth of data from the first on. That data point days were the 1st, 6th, 11th, 16th and the 21st. Each of these days that was chosen also represented a day where all buses were in full use with little to no difference in there operating schedule. This was established as the best way of getting a good variation of data.

We took the data from both filling stations to come up with our X factor for each days worth of data points. This gave us an assortment of total fuel consumed for each ...

As suggested gas consumption is impacting the company financially. Gas consumption is expected to increase within years for Omnitrans. So what should the company do? Many alternatives were given such as utilizing ethanol, methanol, electricity, propane or biodiesel. The company will have to decide what would be financial beneficial to their needs by weighing the costs with the benefits.
