A Multi-Echelon Network Design in a Dual-Channel Reverse Supply Chain Considering Consumer Preference
1Faculty of Economics and Management, Xi'an University of Technology, Xi'an 710048, China.
Summary
Dual-channel reverse supply chains (DRSCs) integrate online and offline recycling. This study models DRSC network design, finding consumer preference positively impacts collection quantity and system profits for economic and environmental sustainability.
Area of Science:
- Operations Research
- Supply Chain Management
- Environmental Sustainability
Background:
- E-commerce growth necessitates integrating online recycling channels with traditional ones, creating dual-channel reverse supply chains (DRSCs).
- DRSCs face challenges in stability and complexity due to factors like consumer preference and service levels, impacting system efficiency.
- Effective network design is crucial for DRSCs to maintain competitiveness and profitability.
Purpose of the Study:
- To develop a quantitative model for designing multi-echelon, dual-objective DRSC networks.
- To incorporate consumer preference for online recycling channels into the network design model.
- To investigate the impact of uncertainty on DRSC network design and find optimal Pareto solutions.
Main Methods:
- Formulated a mixed integer linear programming (MILP) model for DRSC network design.
- Incorporated consumer preference and uncertainty into the MILP model.
- Utilized the ε-constraint method to derive optimal Pareto solutions.
Main Results:
- Consumer preference for online recycling channels positively correlates with total collection quantity.
- Online recycling prices show a positive relationship with system profits.
- The model provides insights into balancing economic and environmental objectives in DRSCs.
Conclusions:
- The proposed MILP model and ε-constraint method effectively address DRSC network design challenges.
- Consumer preference and pricing strategies are key levers for optimizing DRSC performance.
- The findings support recyclers in making informed pricing and service decisions for sustainable operations.

01:23Transmission Line Design Considerations
258
Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

01:20Design Example: Capacitance Multiplier Circuit
1.1K
In integrated circuit technology, a capacitance multiplier is often utilized to produce a larger capacitance value when a small physical capacitance falls short. This is achieved by a circuit that multiplies capacitance values by a factor of up to 1000, such that a 10-pF capacitor can replicate the performance of a 100-nF capacitor.
The circuit illustrated in Figure 1 below incorporates two op-amps, with the first operating as a voltage follower and the second acting as an inverting amplifier.

The fast decoupled power flow method addresses contingencies in power system operations, such as generator outages or transmission line failures. This method provides quick power flow solutions, essential for real-time system adjustments. Fast decoupled power flow algorithms simplify the Jacobian matrix by neglecting certain elements, leading to two sets of decoupled equations:

In circuit analysis, situations often arise where resistors are neither in series nor parallel configurations. To tackle such scenarios, three-terminal equivalent networks like the wye (Y) (Figure 1 (a)) or tee (T) and delta (Δ) (Figure 1 (b)) or pi (π) networks come into play. These networks offer versatile solutions and are frequently encountered in various applications, including three-phase electrical systems, electrical filters, and matching networks.

Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

01:17The Delta-to-Delta Circuit
844
In a delta-delta configuration, the source and the load are connected in a delta manner, forming a closed loop that divides the network into three distinct phases. This configuration makes the phase voltages identical to line voltages. Assuming the sources are in positive sequence, the phase voltages can be expressed directly without having a neutral wire.
