Each response must be 200 words: Response 1: I have selected the following three lessons learned from previous coursework in relation to transportation concepts; fixed and variable costs, demand elasticity and value-added function. Fixed and variable costs Fixed (infrastructure) and variable (operating) costs directly affect production and the overall price of transportation. Rodrigue & Notteboom (2019) specified fixed costs are costs applying to the physical assets of transportation mainly infrastructures, terminals and vehicles. No matter what kind of business a company is in, it must invest in maintaining its physical assets of transportation to perform its operations. In my current profession, I have learned how weight is also a cost function when freight is involved specially when dealing with transshipments, changing the means of transport. Cost associated with maintaining fleets of vehicles and operating costs are also factors to consider when determining transportation cost. Some companies may decide to buy or lease a fleet, while others may prefer to outsource their transportation requirements to 3PLs. Lesson learned; fixed and variable cost are important factors to consider when determining accurate transportation costs Demand elasticity Lessons learned from demand elasticity is how the relation to transportation depend on factors that affect responsiveness of demand to a change. Given that transportation is a product that consumers would be willing to buy at different prices when other things are constant, I would say that transportation demand is price elastic because transportation demand inversely proportionate to price. When the price increases demand decreases and when price decrease demand increases. Factors other than price that make a product elastic can also include substitute products, consumer income, consumer preference and population. As an example, when population and migration increase demand also increase and when the population decrease demand also decreases. Lesson learned; demand elasticity in relation to transportation depends on factors that affect responsiveness of demand change. Value added functions, Many corporations should ask themselves how to build a more efficient supply chain. Rodrigue & Notteboom (2019) detailed four functions within logistics that can help create a more efficient supply chain: production, location, time, and control. The value-added services that production offers to logistics are services within logistics that are provided at little to no additional cost, such as Just in Time (JIT) production. Location is a value added by taking better advantage of various locations with access to more customers and lower distribution costs. Time provides an added value from having goods and services available when required along the supply chain. Control provides value by coordinating cycles, lead times, better marketing, and demand response, thus forecasting demand and allocating re.
