Packaging process selection (on)

〔Abstract〕Introduce the analysis method of packaging process selection, and give a specific analysis example.
Keywords: packaging process; selection In a large number of companies, there are a large number of given resources, to complete the product packaging plan, you need to select the product packaging process, to minimize its cost.
In order to reduce business costs, improve business productivity. An analytical method to optimize the packaging process is given, and this problem is solved by this effective analysis method.
1. Analytical model enterprises In order to complete the product packaging plan, it is necessary to select the product packaging process method so as to minimize the cost. In order to solve this type of problem, the following symbols are first quoted here:
k: the type of packaging products; Pk: the production plan for various types of packaging products; l: the number of packaging products; s: the type of resources allocated; m: the number of allocated resources; bs: the amount of allocated resources j: packaging process type; n: number of packaging process types; cj: using j packaging process, unit packaging costs; ajk: using j packaging process, unit packaging of various packaging product output; bsj: using j packaging Process, unit packaging, demand for s kinds of resources; xj: production strength using j-packaging process.
Based on the above definition, a packaging process optimization analysis model can be established:
Complete the packaging production plan: (k =1,2,...,l)
Use of resources: (s =1,2,...,m)
Non-negative production strength: xj ≥ 0 (j =1, 2, ..., n)
The above analysis model is a linear programming model that can be solved by the simplex method. However, this method is relatively complicated to solve, manual calculation is very difficult, and it is not easy for packaging engineering technicians to use. This article presents a convenient and quick solution method using Solver in Microsoft Excel 5.0 for Windows software.
2. Calculation example A company can package two (l=2) products (k=1, 2); use two (n=2) packaging processes (j=1, 2) to allocate resources (m= 3) Type (s=1, 2, 3), packaging production plan is P1=200 units, P2=660 units.
The allocation of resources: b1 = 97 units, b2 = 54 units, b3 = 100 units, other indicators are listed in Table 1.
