Summary
This study introduces a cooperative game theory model for green supplier selection, incorporating fuzzy logic. Horizontal cooperation in logistics networks reduces costs and benefits companies, optimizing total logistic expenses.
Area of Science:
- Operations Research
- Environmental Management
- Supply Chain Management
Background:
- Multi-criterion decision-making is crucial for supplier selection.
- Green supplier selection integrates environmental considerations into procurement.
- Reverse logistics, eco-design, and circular economy principles are vital for industries.
Purpose of the Study:
- To develop a cooperative green supplier selection model using game theory.
- To incorporate green manufacturing, transportation, and procurement criteria.
- To address uncertainty and fuzzy environments in decision-making.
Main Methods:
- A cooperative game theory approach is applied.
- An optimization model is developed to handle uncertainty.
- A fuzzy rule-based (FRB) system with IF-THEN rules is deployed.
Main Results:
- Horizontal cooperation in logistics reduces overall costs and emissions.
- Fuzzy rule-based systems offer a novel approach to green supplier selection.
- Sensitivity analysis confirms cost savings and benefits from cooperation.
Conclusions:
- Cooperative game theory optimizes logistic networks for green supplier selection.
- Horizontal cooperation leads to increased cost savings for companies.
- The proposed FRB model provides an effective framework for sustainable supply chains.

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...

01:20Criteria for Aromaticity and the Hückel 4n + 2 Rule
11.7K
Like benzene, cyclobutadiene and cyclooctatetraene are cyclic compounds with alternate single and double bonds. However, their chemical behavior differs from benzene, as they are unstable and not aromatic. So, what are the structural characteristics of unsaturated compounds categorized as aromatic?
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as...

Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.

01:34Woodward–Hoffmann Selection Rules and Microscopic Reversibility
3.4K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

01:19Routh-Hurwitz Criterion II

In the application of the Routh-Hurwitz criterion, two specific scenarios can arise that complicate stability analysis.
The first scenario occurs when a singular zero appears in the first column of the Routh table. This situation creates a division by zero issues. To resolve this, a small positive or negative number, denoted as epsilon (∈), is substituted for the zero. The stability analysis proceeds by assuming a sign for ∈. If ∈ is positive, any sign change in the first...
