Designing a Fresh Food Supply Chain Network: An Application of Nonlinear Programming

Algorithm 1

Step 1. Find an initial solution 𝑇_𝑖=1 by inspection.

Step 2. Calculate Π^′(𝑇) and Π^′′(𝑇).

Step 3. Let 𝑇_𝑖+1=𝑇_𝑖−Π^′(𝑇)Π^′′(𝑇).

Step 4. If 𝑇_𝑖+1−𝑇_𝑖≤𝜀, where 𝜀 is the tolerance error, then go to Step 5; otherwise, let 𝑖=𝑖+1 and go to Step 3.

Step 5. Let 𝑇^∗=𝑇_𝑖+1 and Π^∗(𝑇^∗)=Π(𝑇_𝑖+1).

Step 6. Determine 𝐴^∗_𝑖(𝑇^∗) and 𝜏^∗(𝑇^∗) by (8) and (9) respectively.
