The waterfall model is a sequential design process‚ often used in software development processes‚ in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception‚ Initiation‚ Analysis‚ Design‚Construction‚ Testing and Maintenance. The waterfall development model originates in the manufacturing and constructionindustries; highly structured physical environments in which after-the-fact changes are prohibitively costly‚ if not impossible. Since no formal software

There are many transportation processes and modes involved in the supply chain of both coal and manufactured electronic goods although many of these processes differ when comparing the two. The multimodal transportation of coal from the mining site in Australia to the end users in china is a is a large and relatively simple process when compared to transporting manufactured electronic goods from china to the end users in Australia which is a multimodal process. In both cases there will be main

1.2. ACTIVITIES TIMING AND TOTAL FLOAT To determine timing of activities in the network diagram the following calculations were done for each node: Earliest Start-(ES)‚ Earliest Finish-(EF)‚ Latest Start-(LS) and Latest Finish-(LF). Field and Keller (1998‚ p. 191) ES and EF are found by using the forward pass through the network … from the unique project start node and ends at the unique project completion node. ES is the ending day for the previous node/activity‚ where more than one
