This final year project focuses on automating the supply chain for a retailer selling TV sets. The goal is to effectively manage stock levels in warehouses, ensuring timely restocking from manufacturers when inventory falls below set thresholds. Given that supply chain inefficiencies can cost companies up to 20% of their value, efficient software solutions are paramount. The project utilizes jBPM for process design, with MySQL as the database, and addresses challenges related to configuration and version selection. The outcome demonstrates considerable potential for cost savings in retail operations.

  1. Supply Chain Automation Final Year Project

  2. What is this project about? • The application to be modeled is that of a Retailer offering TV sets to Consumers • To fulfill orders the Retailer has to manage stock levels in warehouses • When an item in stock falls below a certain threshold, the Retailer must restock the item from the relevant Manufacturer’s inventory

  3. Is it really needed? • A recent study found that supply-chain problems cost companies between 9 and 20 percent of their value over a six-month period • Effective supply-chain software tools could save companies billions of dollars • Reliable

  4. How we built the project? • The process was suggested to be designed in jBPM • The business process was analyzed and a flow diagram was designed on paper • The flow diagram was then implemented using the Graphical Process Designer for jBPMconfigured in Eclipse IDE • MySQL was configured as the database for jBPM • jBoss AS was configured to run the jBPM process • Dynamic Web Project was created for UI pupose

  5. Challenges • Which version of jBPM to be used? • jBPM 4 vsjBPM 3 • jBPM4 tools are only half finished and quite buggy • The original 'brain' of JBPM has left Redhat and is now working on a competing open source API under the name of 'Activiti‘ • Apparently Redhat also already has JBPM5 in development;JBPM4.x is given up for lost for now and the focus for the tool development will be on JBPM5 • All is fine and well, but we all want is a working JBPM API that DOES have functional tools. So we stick with old JBPM 3.2.X, which has served well

  6. Challenges (Cont.) • Configuring jBPM 3.2.x with jBoss 5.0 • Fixing jbpm-enterprise.jar • The main problem we needed to fix here is the way that the JNDI lookups are done - it tries to use the java:comp/env space, which is off-limits unfortunately • We needed to patch some source files to use the real local JNDI names to get things working • Luckily we know these JNDI names; they are defined in the jboss.xml descriptor file • Configuring jBoss Data Source file for MySQL

  7. Challenges (Cont.) • Which database to be used? • Although MySQL was directly suggested its important to know why we need to use MySQL when default configuration with HSQL is easier than configuring another database with jBPM • HSQL vsMySQL • Hypersonic is a memory-resident test database. The fact that all data is kept in memory accounts for the speed difference.(HSQL is faster) • But would HSQL behave well in real situations?(Doubt, implies Not reliable) • MySQLis a free 'real' database in the sense that it is used in many production systems and is tested to be reliable.

  8. Into the future • Source code hosting with SVN • The project we developed serves on a smaller scale and has a large scope of development to serve the industry • Keeping this in mind we have hosted the project on http://code.google.com/a/eclipselabs.org/p/supply-chain-automation/
