Econometrica, 1951
WE ipropose to outline a method for deriving optimal rules of inventory policy for finished goods. The problem of inventories exists not only for business enterprises but also for nonprofit agencies such as governmental establishments and their various branches. Moreover, the concept of inventories can be generalized so as to include not only goods but

Proximal Policy Optimization With Policy Feedback
IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2022Proximal policy optimization (PPO) is a deep reinforcement learning algorithm based on the actor-critic (AC) architecture. In the classic AC architecture, the Critic (value) network is used to estimate the value function while the Actor (policy) network optimizes the policy according to the estimated value function.

Management Science, 1974
The value of a collateralized loan subject to default is obtained using a dynamic programming approach. The optimal foreclosure policy for a special case is derived based on the number of payments which are late. These results are then applied to an example taken from a casebook on financial institutions.

On Optimal Replacement Policies
Management Science, 1982A system (e.g., a car) must operate for the next t time units. A certain component (e.g., a battery) must be replaced whenever it fails, as it is essential for the operation of the system. There are several types of components differing only in price and life distribution.

This paper describes and analyses a bi-level Markov Decision Problem (MDP). The model has been used to study questions on the setting of fisheries quota. The problem extends earlier models in literature and describes fish stock and economic dynamics. At the first level, an authority decides on the quota to be fished keeping in mind long term revenues ...

IEEE Communications Letters, 2008
We investigate the problem of resource allocation in heterogeneous networks of computational resources. We provide an explicit analytical solution for a situation where the computational environment can be described by M/M/l queueing theory. We illustrate the quality of our solution by comparing results with those obtained via a simple ad hoc resource ...

Optimizing interconnection policies
Computer Networks, 2004There are two basic types of interconnection agreements between providers in the Internet: peering and transit. A decision every Internet network service provider (INSP) has to make is which other peering/transit INSPs to connect with. The potential peering/transit partners offer (obviously) different routes and they may differ quite drastically in the

Economic Inquiry, 2023
AbstractThis paper shows that the optimal policy to deal with unemployment features important roles for monitoring of search and job search assistance, with the optimal combined policy also incorporating more generous unemployment insurance (UI). These results are significantly different from the previous literature, which has overwhelmingly focused on

The Existence of an Optimal Economic Policy
Econometrica, 1969Summary: In this paper the general mathematical structure of most long term economic policy problems is indicated. For such a general policy problem the existence of optimal policy is established under certain conditions. In the proof of the existence theorem presented in this paper, compactness of the set of feasible policies is established using ...

Optimal Policies for Economic Stabilization
Econometrica, 1973SOME FIFTEEN YEARS have passed since Phillips [15] first showed that the application of certain types of stabilization policies to multiplier-accelerator macroeconomic models could result in undesired oscillations or instabilities. It has become clear from this and other analyses of macroeconomic policy [1, 3, 5, 16] that, because of the dynamic ...
