If you operate a flour mill, the last thing you may ask is having a halt in the production as the shortest halt you have may cause serious losses in your production and lower your efficiency in today’s intensely competitive market. An efficient and smooth operation of a production facility is closely related with the accuracy of the feasibility made for that facility, transfer and application of the results obtained that feasibility to the facility design with the smallest detail. No matter in which sector, producers desire nonstop operation of their facilities without causing halts in the production; development, renewal and maintenance of their facilities without interrupting production when necessary as any halt or problem in the production in today’s markets in which there is intense competition can cause serious tangible and intangible losses for the companies.
