Abstract—This paper discusses the problem of having excess inventory in small retail businesses in the Philippines. Extreme excess inventory is usually the result of the culture of having an oversupply by small retail businesses in the Philippines. To address this, a simple, structured, and easyto-use method for determining production level is proposed. The proposed methodology lowers the excess inventory at the end of the day. However, shortages that were not experienced in the past via the businesses’ trial-and-error methodology, should still be expected with the proposed methodology but these can be anticipated to be low in occurrence.
