The rounding of orders to achieve a batch size is recognised as a source of the bullwhip problem within supply chains. While it is often advocated that batch sizes should be reduced as much as possible, there has been limited investigation into the impact of batching on bullwhip. Here we consider scenarios where orders are placed only in multiples of a fixed batch size, for both deterministic a...

Both software-initiated and hardware-initiated prefetching have been used to accelerate shared-memory server performance. While software-initiated prefetching require instruction set and compiler support, hardware prefetching often require additional hardware structures or extra memory state. The coherence batching scheme proposed in this paper keeps the system completely binary transparent and...

In this note we consider a new problem, the so-called bin-batching problem related to variablesized bin covering. A best possible on-line algorithm is presented. ? 2001 Elsevier Science B.V. All rights reserved.

We introduce a homomorphic batching technique that can be used to pack multiple ciphertext messages into one ciphertext for parallel processing. One is able to use the method to batch or unbatch messages homomorphically to further improve the flexibility of encrypted domain evaluations. In particular, we show various approaches to implement Number Theoretic Transform (NTT) homomorphically in FF...

Mavres Petres mine is an underground mine, located in Chalkidiki, northern Greece, that owned and operated by Hellas Gold; a wholly subsidiary of Eldorado Gold Corporation. The extracts highgrade lead zinc orebody using drift fill mining method. Backfill integral part cycle at mine. Filtered coarse tailings mixed with cement are used for making cemented hydraulic backfill surface batching plant...

Recent advances in Information and Communication technologies have made multimedia on demand services technically and economically feasible. An important aspect of such systems is the resource sharing technique, which allow the contemporaneous service of a large number of user requests with a considerable saving in terms of network bandwidth and server resources. In this paper, we report the re...

This paper discusses a two-stage assembly-type flowshop scheduling problem with batching considerations subject to a fixed job sequence. The two-stage assembly flowshop consists of m stage-1 parallel dedicated machines and a stage-2 assembly machine which processes the jobs in batches. Four regular performance metrics, namely, the total completion time, maximum lateness, total tardiness, and nu...

We present an algorithmic approach for speeding up SSL’s performance on a web server. Our approach improves the performance of SSL’s handshake protocol by up to a factor of 2.5 for 1024-bit RSA keys. It is designed for heavily-loaded web servers handling many concurrent SSL sessions. We improve the server’s performance by batching the SSL handshake protocol. That is, we show that b SSL handshak...

In e-commerce markets, on time delivery is of great importance to customer satisfaction. this paper, we present a Deep Reinforcement Learning (DRL) approach for deciding how and when orders should be batched picked in warehouse minimize the number tardy orders. particular, technique facilitates making decisions whether an order individually (pick-by-order) or batch with other (pick-by-batch), i...
