1 - Multi-depot Two Echelon Pollution Minimizing Routing Problem
With Heterogeneous Vehicles

, Gitakrishnan Ramadurai
A new variant of VRP to find the heterogeneous fleet mix and routes at two
levels by jointly minimizing the operational and pollution cost is proposed. Fuel
consumption and the pollutants emitted are a function of load, speed, and
acceleration characteristics. A mixed-integer program is formulated and an
effective metaheuristic solution algorithm is presented.
2 - Heuristics For Online Orders Delivery Optimization

E-commerce became a global trend and its volume has been expanded
remarkably. Consumers can order products to be delivered at their homes. These
online ordered products are supplied from the retail stores available inventories.
The retail stores require products from central warehouse as well. In this paper
we consider the vehicle routing problem for the delivery of products ordered
online and the delivery of products from central warehouse to retailers. We
provide mathematical description and heuristics to solve the problem. Numerical
experiment is performed on randomly generated problem instances to evaluate
the heuristics performance.

1 - Financing Schemes For Upstream Suppliers

We consider four financing schemes for a supplier with limited capital: bank
loans, purchase order financing (POF), retailer loans and advance payments. We
model players’ interaction as Stackelberg games. We show that: (1) The bank loan
helps the supplier to overcome the capital constraint and produce its desired
quantity. (2) While the production quantity in retailer loans or advance payments
can be either lower or higher, the one under POF is always higher than the
supplier’s desired quantity. (3) No scheme is dominating in terms of players’ own
and chain’s sake. (4) Different from retailer loans and advance payments, POF
allows each player to obtain profits larger than that under bank loans.
2 - Optimizing Joint Replenishment Problem For Non-instantaneous
Deteriorating Items With Multiple Suppliers Offering
Quantity Discounts
Xueyi Ai, Huazhong University of Science and Technology,
Luoyu Road, NO. 1037, Wuhan, China, Wuhan, 430074, China,
, Jinlong Zhang
This paper deals with a new joint replenishment problem, in which a number of
non-instantaneous deteriorating items are replenished from several suppliers
under different quantity discounts schemes. We develop a model integrated with
a supplier selection system and the joint replenishment programmes for non-
instantaneous deteriorating items. An improved moth-flame optimization (IMFO)
algorithm is proposed to solve this NP-hard problem so that the total cost is
minimized. Numerical examples are shown to illustrate the performance of IMFO
algorithm. Extensive experiments are performed to further investigate the
effectiveness of the proposed algorithm.
3 - Management Of Supply Chains With Perishable Assets
Maxim A. Dulebenets, Assistant Professor, Florida State University,

Mihalis Golias, Mehdi Amini
Nowadays many of supply chains deal with design, production, distribution, and
retailing of perishable assets. Perishable assets may deteriorate due to certain
external factors, such as time, temperature, humidity, pressure, power, air
composition, etc. This presentation will focus on the key features of supply chains
with perishable assets, attributes of perishable assets, sustainability of supply
chains with perishable assets, best practices revealed in the relevant scientific
literature and applied in the industry, and outline some critical issues and
potential directions for the future research.
4 - Designing Power Supply Chains- Understanding India’s
Electrification Underachievement And Disparity
Prateek Raj, PhD Student, University College London,
Gower Street, UCL School of Management, London, WC1E 6BT,
United Kingdom, , Achal Bassamboo
Power supply has a complex supply chain. It involves coordination between
several players for both everyday operations and for long term planning. We
consider different ways of organizing decision making in power supply chains,
and study the varying outcomes in capacity and efficiency of power supply. Using
this framework, we study why India has lagged behind in rural electrification
compared to other large countries. We also explore why there is high
heterogeneity in rural electrification within India.

1 - Queue Joining Decisions When There Is A Prerequisite Condition
For Getting Service
Mona Imanpoor Yourdshahy, PhD Student, University of British
Columbia, 2053 Main Mall, Vancouver, BC, V6T 1Z2, Canada,
, Woonghee Tim Huh,
Steven Shechter
We consider an M/M/1 queueing system in which a customer requires some
prerequisite condition to be met prior to receiving service. We investigate whether
an individual arriving to this system should join the queue at that time, or wait to
join at some future time. We formulate this problem as a Markov decision process
and show how the structure of the optimal policy depends on in-queue and out-
of-queue waiting costs, the arrival and service rates, as well as the time until the
prerequisite condition is satisfied.
2 - Codified Knowledge Sharing And Operational Failure In
Healthcare: Evidence From NHS Hospitals’ Risk
Management Documents
Bilal Gokpinar, University College London, London, United
Kingdom, , Mecit Can Emre Simsekler
Focusing on codified knowledge sharing among healthcare personnel in the form
of written documents (e.g. risk management policies, procedures, strategies, etc.),
we examined the role of the nature and content of codified knowledge on risk
management performance. We used a unique dataset from NHS acute trusts in
England and employed text-mining techniques to investigate the impact of
documents on risk management.
3 - Study On The Scheduled Bus-bridging Service And Emergent
Strategy Of Bus Fare Discount Under Operation Disruptions Of
The Metro System
Li_bing Wan, Huazhong University of Science&Technology,
Wuhan, China,
The rail transit has many advantages, at the same time, it also often fails and
operation disruptions . This thesis studies the bus-bridging evacuation service for
complete passengers’ travel and the emergent strategy of bus fare discount under
operation disruptions of the rail transit. Firstly, we systematically summarize and
analyze operation disruptions of three cities . Secondly,the conventional metro-
bus evacuation equilibrium model is established . Thirdly, the thesis deeply
researches the effect of bus fare discount to the original equilibrium and
determines optimal bus fare discount strategies for two different targets.
