Summary
This study introduces a green supply chain management framework integrating dynamic simulation and lifecycle assessment (LCA) to evaluate environmental and economic impacts. It aids in optimizing supply chain decisions for sustainability.
Area of Science:
- Environmental Science
- Operations Research
- Industrial Engineering
Background:
- Environmental sustainability is a key business driver, necessitating tools for assessing manufacturing and supply chain (SC) impacts.
- Lifecycle Assessment (LCA) measures product environmental consequences but often lacks SC dynamics and multitiered interactions.
- Existing methods provide a high-level view, omitting crucial dynamic and interactive SC elements.
Purpose of the Study:
- To propose an integrated framework for green supply chain management.
- To evaluate economic and environmental impacts of SC decisions using dynamic simulation and LCA.
- To provide decision support for optimizing green SC design and operations.
Main Methods:
- Integrated a supply chain (SC) dynamic simulation with Lifecycle Assessment (LCA) indicators.
- Developed a framework for evaluating SC decisions like inventory, distribution, and ordering policies.
- Utilized an industrially motivated case study for diaper production to demonstrate the framework.
Main Results:
- The framework enables integrated decision support for green SC design and operation.
- Demonstrated the evaluation of economic and environmental impacts for various SC strategies.
- Highlighted the benefits through analysis of three distinct production scenarios.
Conclusions:
- The proposed framework effectively integrates dynamic simulation and LCA for comprehensive green SC management.
- This approach offers enhanced decision support for balancing economic and environmental objectives in SCs.
- The study provides a practical tool for companies aiming for sustainable manufacturing and supply chain operations.

01:09Decision Making: P-value Method
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...

01:21Manipulation and Analysis
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
