Optimizing model for agile product development in garment industry

Purpose: This research aims to determine an optimal plan for product development process. The developed product is a sustainable product with an agile concept. Mathematical models are involved to determine the optimal value of the number of product ideas and it is profits. The mathematical model will be of beneficial to create product development process strategies.Design/methodology/approach: This article develops a mathematical model of integer linear programming using LINGO 18.0 software. The results of the mathematical model to get the best value are maximizing profits by considering the number of product ideas. In determining profits, this research uses idea prices and idea costs. Total profit is the total income from realizing the product idea minus the total costs of realizing the product idea.Findings: This research creates a mathematical model of the product development process in the garment industry. The sustainable products studied are garment products. The product development process consists of five mathematical model scenarios. The best model result is the fifth scenario, namely, the value of the number of product ideas is six units, and the profit value is IDR1220000.Research limitations/implications: This research discusses one stage of the product development process. This stage is the planning stage. Research can be developed by discussing all stages of the product development process.Practical implications: The mathematical models will help product development teams maximize profits among product ideas.Social implications: The discussion of the mathematical model can be applied to other garment industries.Originality/value: The product development process requires a mathematical model, namely a linear integer, to maximize profits from the number of sustainable product ideas.
