An inventory model of two-warehouse system with variable demand dependent on instantaneous displayed stock and marketing decisions via hybrid RCGA

The two-warehouse material location selection problem

“…Also, it provides both an explicit material receiving policy and a material storage policy, so that workers can determine directly where to look for each material. This policy is similar to the common practice considered in the two warehouse inventory modeling problem (Bhunia and Maiti, 1998;Zhou, 2003;Yang, 2004;Bhunia et al, 2011;Liang and Zhou, 2011) in which the items stored in the rented warehouse are consumed first or continuously transferred to the owned warehouse. However, the material level flexible storage policy may not achieve the same level of stock rotation as the material level, since it allows for keeping onsite materials in separate locations.…”

“…The two warehouse inventory modeling problem was introduced by Hartley (1976) and later was developed to include realistic aspects of the inventory system, such as item deterioration (Bhunia and Maiti, 1998;Yang, 2004Yang, , 2006Rong et al, 2008;Hsieh et al, 2008;Lee and Hsu, 2009;Thangam and Uthayakumar, 2010;Liang and Zhou, 2011), and backlogging (Goswami and Chaudhuri, 1992;Bhunia and Maiti, 1998;Zhou, 2003;Yang, 2004Yang, , 2006Rong et al, 2008;Hsieh et al, 2008;Jaggi and Verma, 2008). In addition, other issues such as stock-level dependent demand (Zhou and Yang, 2005;Mondal et al, 2007;Bhunia et al, 2011), item quality (Chung et al, 2009) and trade credit (Thangam and Uthayakumar, 2010;Liang and Zhou, 2011) are incorporated to reflect different cases of the inventory system. Different from the classical models that focus on the inventory level of a single item, Maiti et al (2006) introduced a nonlinear model and applied real-code genetic algorithm to solve a variant of the problem, which involves multi-item inventory levels.…”

An application of PSO in a two-warehouse inventory model for deteriorating item under permissible delay in payment with different inventory policies

“…On the other hand, a good number of works have been published for two warehouse inventory system. In this area, the recent works of Das et al [12], Niu and Xie [13], Rong et al [14], Dey et al [15], Hsieh et al [16], Maiti [17], Jaggi and Verma [18], Lee and Hsu [22], Jaggi and Aggarwal [23], Bhunia and Shaikh [26], Bhunia et al [27], Jaggi et al [28], Yang [30], Bhunia et al [31], Bhunia et al [32], Yang and Chang [33] are worth mentioning. The details about these works have been shown in Table 1B.…”

An inventory model for defective items with trade credit and inflation

“…Geetha and Uthayakumar (2009) developed an optimal inventory control policy for items with time-dependent demand. Bhunia, Pal, Chattopadhyay, and Medya (2011) investigated an inventory model of two-warehouse system with variable demand dependent on instantaneous displayed stock and marketing decision via hybrid RCGA. Soni and Patel (2012) discussed an optimal strategy for an integrated inventory system involving variable production and defective items under retailer partial trade credit policy.…”
