John White, vice president of distribution for W-G-P Chemical Company, was preparing for the annual strategy review session conducted by the firm’s executive committee.

W-G-P Distribution Systems
Figure 1 outlines the existing logistics system for W-G-P Chemical Company. Four types of facilities: (1) two continuous, company-owned manufacturing plants; (2) nine seasonal contracted manufacturing plants; (3) numerous in-transit distribution centers; and (4) 28 full-time distribution centers. Growing environmental activism has influenced management to reject any relocation of the manufacturing plants.
W-G-P distributes 129 different products or SKUs on a national basis. For distribution considerations, the products may be grouped into two different categories. Category A consists of 13 SKUs of a product called Prevention. The sales of Prevention are highly seasonal and account for 85 percent of W-G-P’s total revenue. The 116 Category B products (called Support) sell throughout the year but also have a seasonal pattern similar to that of Prevention’s sales. Although the sales volume of Category B is only 15 percent of W-G-P’s total revenue, this group of products contributes approximately 30 percent of total before-tax profits. The typical end user of W-G-P’s products purchases a variety of both A and B products. In many cases, the products are used jointly in agricultural applications.
W-G-P’s total product line is marketed through a network of agricultural dealers. The company sells to the dealers, who then resell the products to farmers. The typical dealer provides farmers with a broad line of products, including those that are directly competitive with W-G-P products. Historically, farmers tend to purchase both A and B products 1 to 2 weeks before field
