Dear Employer,
I am an excel developer with the Retail business / Supply Chain / Inventory control / Replenishment Planning and Sales Data analysis back ground. I always use Excel both excel standard and VBA coding to design the simulation model for the business and also create the dynamic Spreadsheet for users to use.
You can see more of my profile and expertise here: my project feedback in http://www.freelancer.com/users/feedback_2698784.html
I have read your requirement and here are what I plan to do for your business...
1) This will not only be the forecast of resource requirement, but the model will give the Optimum point of cost consumption, related to the work load each day VS available resource VS Cost per Head Count.
2) This model will allow you to maintain / modify the driver availbility and Cost of each driver, of course work load capacity each day, too.
3) Of course the model can be automatically adjusted by the input information.
Hope you like this model and to have chance working with you.
Thanks,
Pichart Y.
