Abstract

Penalty function is a key factor in interval goal programming (IGP), especially for decision makers weighing resources vis-à-vis goals. Many approaches (Chang et al. J Oper Res Soc 57:469-473, 2006; Chang and Lin Eur J Oper Res 199, 9-20, 2009; Jones et al. Omega 23, 41-48, 1995; Romero Eur J Oper Res 153, 675-686, 2004; Vitoriano and Romero J Oper Res Soc 50, 1280-1283, 1999)have been proposed for treating several types of penalty functions in the past several decades. The recent approach of Chang and Lin (Eur J Oper Res 199, 9-20, 2009) considers the S-shaped penalty function. Although there are many approaches cited in literature, all are complicated and inefficient. The current paper proposes a novel and concise uniform model to treat any arbitrary penalty function in IGP. The efficiency and usefulness of the proposed model are demonstrated in several numeric examples.
