“…El Saadany et al [16] investigated a two-echelon supply chain model with price and product's environmental quality dependent demand. Wahab et al [17] developed a lot size inventory model with environmental considerations. Their main focus was on reducing CO 2 emission in inventory transportation.…”

Carbon emissions play the central role in global warming. Manufacturing firms are significant contributors to carbon emissions. In many countries, regulatory authorities are taking actions to reduce emissions. Carbon taxation and cap-and-trade schemes are two mechanisms implemented in many countries. In the present paper, the author analyzes a production-inventory model under a carbon tax system. The production rate is assumed to be a decision variable and can be set at any level within machine limits. A proportion of items produced are defective, and this proportion depends on the production rate. Demand depends on the selling price. Unit price is a decreasing function of the production rate. Emissions can be reduced to some extent by capital investment on green technology, and this capital investment amount is a decision variable. Customers are categorized as retail customers and wholesale customers. A discount is offered to the wholesale customers on the regular selling price. The results are illustrated by a numerical example and a sensitivity analysis is performed.

“…However, their model has some shortcomings, including no calculation of the social costs of vehicle emissions and no examination of the effect of transportation mode selection. Wahab et al [9] partly examine the impact of considering the environment on the optimal production-shipment policy for items of imperfect quality in a two-level supply chain. In the model, they divide CO 2 emission costs into fixed and variable costs.…”

Sustainable EOQ under Lead-Time Uncertainty and Multi-Modal Transport

Abstract:In this paper, we examine a sustainable economic order quantity (S-EOQ) problem with a stochastic lead-time and multi-modal transportation options. With the S-EOQ, decisions of order quantities, as well as a reorder point could be influenced by various factors, including unit price, stock-out cost, lead-time variability and emission costs. For a better understanding, we present a mathematical model of the concomitant S-EOQ problem and, using numerical experiments, explore various scenarios to determine the effects of incorporating sustainability considerations into the traditional inventory model on operational decisions including the choice of transportation modal combination and the sourcing decisions

“…carbon emission through a cap-and-trade system under the assumption that carbon emission is linear with the order quantity. Wahab et al (2011) developed mathematical models: a domestic and an international supply chains that took the environmental impacts. Benjaafar et al (2012) and Chen et al (2013) developed emission constraints to a single-level lot sizing (EOQ) and an integrated lot sizing models with the dynamic demand under different carbon emission policies (carbon emission tax, inflexible cap, the cap-and-trade) and analyzed the trade-off between costs and emissions.…”

This paper presents a joint economic lot size model for a single manufacturer-a single buyer. The purposed model involves the greenhouse gas emission from industrial and transport sectors. We divide the emission into two types, namely the direct and indirect emissions. In this paper, we consider the Government's penalty and incentive policies to reduce the emission. We assume that the demand of the buyer is normally distributed and partially backordered. The objective is to minimize joint total cost incurred by a single manufacturer-a single buyer and involves the transportation costs of the freight forwarder. Transportation costs are the function of shipping weight, distance, fuel price and consumption with two transportation modes: truckload and lessthan-truckload shipments. Finally, an algorithm procedure is proposed to determine the optimal order quantity, safety factor, actual shipping weight, total emission and frequency of deliveries. Numerical examples and analyses are given to illustrate the results.
