This paper examines the fixed-charge transportation problem through a practical case study of a lampshade company bidding on an overseas export order. The analysis compares three distinct scenarios that vary manufacturing design, packaging density, and transportation methods. Each scenario presents different trade-offs between manufacturing costs, packaging expenses, land transportation, insurance, and overseas shipping. The paper evaluates total costs across all three options and provides a recommendation based on cost minimization principles.
When calculating costs to manufacture and transport goods to a foreign country, it is necessary to consider a number of variables. As one recent paper states, "In the fixed-charge transportation problem, the goal is to optimally transport goods from depots to clients when there is a fixed cost associated to transportation" (Van Vyve, 2013, p. 371). In the proposed scenario contained herein, a lampshade company wishes to bid on an order to be shipped overseas. The company must determine which of three separate designs would provide the most efficient and profitable bid. The three scenarios offer the company the opportunity to use already-designed shades or design new shades that will be more economical to ship. Understanding these cost variables is critical to supply chain optimization and competitive bidding.
Scenario A: Current Design (Single-Shade Packaging)
The first scenario represents the company's current manufacturing and packaging approach. For 5,400 shades with individual packaging:
Scenario B: Optimized Design (Six-Shade Packaging)
The second scenario consolidates packaging by grouping six shades per package, reducing the total number of packages from 5,400 to 90. This approach increases manufacturing costs but reduces packaging and logistics expenses:
Scenario C: Maximum Consolidation (Ten-Shade Packaging)
The third scenario takes consolidation further, packing ten shades per package and reducing packaging units to 54. While this approach minimizes shipping and packaging transactions, it significantly increases manufacturing costs:
