Application of Dynamic Programming Model to Production Planning, in an Animal Feedmills.

The problem of this study is that of determining the quantity of products to produce and inventory level to carry from one period to the other, with the objective of minimizing the total costs of production and the annual inventory, while at the same time meeting the customer’s demand. A mathematical model was formulated for a multi-product problem using Dynamic Programming approach. The model was solved using the solution procedure proposed by Wagner and Whitin. The results show that the minimum total cost will be achieved with production in periods 1, 2, and 4. While demand for period 3 are satisfied with inventory from period 2. The total cost of this plan is N225, 704, 210.00, which is N6, 155, 765.00 less than the existing plan. Keywords: Inventory, Model, Periods, Plan, Cost

AN IOT BASED WEATHER STATION USING AN EMBEDDED SYSTEM

The realtime monitoring system was connected to a microcontroller embedded with a Wi-Fi module (NodeMCU/ESP8266), a temperature and humidity sensor (DHT 11), and a light-dependent resistor (LDR). This device is designed as a platform to provide adequate information for immediate and future weather forecasts. The measured parameters are sent to an open-source IoT analytics platform (ThingSpeak), recorded in the channel, and were downloaded for analysis purposes. The temperature and humidity level were monitored using the Things View Android application and can be accessed by anybody once given the Thing Speak channel ID. Weather data was easily viewed and it can aid in appropriate planning. This IoT-based system will help keep up with the demand of the ravaging global warming with the provision of real-time data for planning towards land preparation and crop planting and for other purposes that are weather dependent.Peer reviewe
