Item Development of a Linear-Model based Computer Software for Least Cost Poultry ration formulation(University of Kelaniya, 2008) Piyaratne, M.K.D.K.; Dias, N.G.J.; Attapattu, M.This study was based on the development of a user friendly, linear-model based computer software system for least cost poultry ration formulation. The software developed in this work used most recent advancements in the field of poultry nutrition and feeding, and developed to suit the local conditions. Sixty locally available feed ingredients were used and thirty nutrients which are most important to poultry growth were considered. Standard linear programming (LP) model for least cost ration formulation was used to analyze and determine the most efficient way of compounding the least cost ration. A mathematical model was constructed, taking into consideration nutrient composition of each of the available ingredient, costs and nutrient requirements of the birds2• Since the ideal protein (IP) concept is becoming popular as a mean of increasing the utilization efficiency of dietary proteins by poultry, NRC (N ational Research Council) and IICP (Ideal Illinois Chick Protein) ideal proteins were also included in broiler rations for calculations. Therefore, although the initial database was based on NRC recommendations users can freely customize ingredient levels and nutrient requirements as and when they required. Ration balancing can be done with 100% equal requirements up to 10-12 major nutrients based to least cost. The standard nutrient requirement levels can be customized and researchers can do experiments with different requirement levels. Therefore, this software can be a very useful tool for researchers, nutritionists as well as teachers. Amino acid profile selection feature allows researchers to formulate experimental rations with various amino acid levels and protein levels. The software can be run under Microsoft Windows environment and users are able to print and save results as well as initial database information. The software has been successfully installed, tested and evaluated successfully with several research projects.Item Interactive communication platform(University of Kelaniya, 2008) Jayaweera, A.J.P.M.P.; Dias, N.G.J.In this research, we put forward a new Concept of Interactive Communication Platform. Since remote IT infrastructure management is a new trend and an expanding area in the field of Information Technology. Communication is becoming a key factor of this new trend. The main objective of this concept is to design, build and develop a program suite for Interactive Communication infrastructure. Since communication is important in all aspects, communication should be fast, efficient and affordable. This program suite is capable of providing communication framework with cost benefits, reduce human intervention and reduce conventional paper usage by providing electronic data. Implementation of the interactive communication infrastructure has achieved by using three available advance communication technologies, which are fast, reliable and secure enough to work interactively on the platform. The implementation architecture described here based on the Electronic mail, Short Message Service (SMS) and XML Web services. The implementation of the interactive communication mechanism achieved dynamically by defining a set of instructions (Mail Rules) and based on a set of defined Protocols. The Mail Ruling system has described in terms of the two mechanisms Auto Reply Email and Mail Alert SMS, the set of protocols Auto Reply Email, Mail Alert SMS, Mail Reply SMS and SMS Mail defined for the implementation. Further, the implementation of the application suite was successful in the experimental domain and hence able to expand the boundaries and limitations in the individual communication mechanism. The main factor behind the success is a combination of widely expanded SMS technology with email, the efficiency and reliability of the communication improved by a significant percentage due to the combined platform.. Furthermore, the expected cost benefits was successfully achieved by the interactive communication framework. The system would be useful to wide verity of users, any individuals or any organizations to optimize their communication framework and increase the reliability and the efficiency of the communication. This framework could be able to push the communication mechanism to get the respond fast from the receiver to sender.Item An inventory control system with intelligent demand forecasting Facility(University of Kelaniya, 2008) Chandima, A.V.L.; Dias, N.G.J.An inventory control system is an integrated package of software and hardware used in warehouse operations, and elsewhere, to monitor the quantity, location and status of inventory as well as the related shipping, receiving, picking and put away processes. In common usage, the term may also refer to just the software components. An inventory control system may be used to automate sales, forecasting the demand of items and monitor the inventory related data. Demand Forecasting is the activity ofestimating the quantity of a product or service that consumers will purchase. Demand forecasting involves techniques including both informal methods, such as educated guesses, and quantitative methods, such as the use of historical sales data or current data from test markets. Demand forecasting may be used in making pricing decisions, in assessing future capacity requirements, or in making decisions on whether to enter a new market. Superinventory is a stand alone software suit consists of lot of functional capabilities developed by StarTech Enterprises Pvt. Ltd. Superlnventory consist of two sub systems they are import document management system and inventory control system. Under inventory control system it provides more convenient and up to date information to support the management process. Intelligent Demand forecasting facility is another option included in this system in order to facilitate the management to predict the future demand of the companies imported goods so that they can easily decide what should be imported, quantity that they need to import, etc. Two past year historical sales data was analyzed using Winter's forecasting model and forecast the demand of sales next two years in the company. Import document management system was decided that the storage of files can be achieved through a file cabinet and the copy of the arrangement can be maintained in the system to facilitate the users with advance searching facilities to locate the files easily. Another facility included in this system is the vendor selection expert. This will facilitate the users with the relevant information and assist the user in selecting the vendors who are capable of supplying the needed items. Here the vendors were recorded as and when they are introduce to the system through registration and record both the specialty and general production items. When user want to find the suitable vendor for the imports he/she just have to select the item and the system will automatically prompt the user with the available vendor options. Superlnventory was developed on the Microsoft Dot Net framework 1.1 with Visual C# for standalone windows application development. Database was developed using SQL server 2000.
