Edit request: add History section

This edit request by an editor with a conflict of interest was declined. Some or all of the changes weren't supported by neutral, independent, reliable sources. Consider re-submitting with content based on media, books and scholarly works.

I am Andrew Siprelle, founder of: - Simulation Dynamics, Inc. (SDI), and - ChiAha, Inc. I am the originator of the discrete rate simulation technique. I have a conflict of interest with this article and am submitting this edit request rather than editing directly per WP:COI.

The article currently does not describe the origin or history of the technique. I propose adding a "History" section between the lead and "Areas of application", with the following text. All claims are supported by published, peer-reviewed sources.

History

Latest comment: 28 days ago4 comments2 people in discussion

The discrete rate simulation paradigm was introduced by Andrew Siprelle in 1990 to address the limitations of conventional discrete event simulation in modeling high-speed continuous-process and bulk-flow manufacturing systems, where unit-by-unit event tracking is computationally prohibitive and dynamically inaccurate.^[1] The first peer-reviewed publication of the technique appeared at the 1995 Winter Simulation Conference under the title Modeling a Bulk Manufacturing System Using Extend.^[1]

The methodology was developed across a series of further Winter Simulation Conference papers through the late 1990s and early 2000s — including the 2002 Non-Item Based Discrete-Event Simulation Tools^[2] — and a 2016 Springer chapter comparing it head-to-head with conventional discrete event simulation.^[3] In 2020, the technique's accuracy was independently assessed in a Winter Simulation Conference paper by Tom Lange (formerly Director of Modeling and Simulation, Procter & Gamble Corporate R&D) and J. Fischel, which reported validation within 1% [[Overall equipment effectiveness|overall equipment effectiveness]] on real production lines.^[4]

Edit request declined

As the proposed claims concern being the "originator" of this techique, we're going to require sources that are not written by the individual making the claim.

The user below has a request that an edit be made to Discrete rate simulation. That user has an actual or apparent conflict of interest.
The requested edits backlog is very high. Please be extremely patient. There are currently 611 requests waiting for review.

Please read the instructions for the parameters used by this template for accepting and declining them, and review the request below and make the edit if it is well sourced, neutral, and follows other Wikipedia guidelines and policies.

Thank you for the review — understood, and I agree that per WP:SELFPUB a priority claim should not rest on my own publications. Below are independent, peer-reviewed sources authored by the commercial ExtendSim vendor (Imagine That Inc.), with no connection to me, that attribute the origin of the technique:

1. Damiron, C. and D. Krahl. 2014. "A Global Approach for Discrete Rate Simulation."

Proc. 2014 Winter Simulation Conference, §2.2: "The first generation DRS tool was developed in the early 1990's when it was recognized that a new simulation methodology was needed (Siprelle and Parsons 1995). Termed 'discrete rate simulation' (Siprelle et al. 1999), this new architecture utilized the discrete event clock but moved flow through the system at rates that maintained mass balance."

2. Damiron, C. and A. Nastasi. 2008. "Discrete Rate Simulation Using Linear

Programming." Proc. 2008 Winter Simulation Conference, p. 740: "The first generation DRS technology was introduced by Simulation Dynamics Inc. in 1997 (Siprelle, Phelps 1997). Taking lessons learned from this ground-breaking technology, a second generation DRS technology has now been developed and is incorporated in the Rate library of the ExtendSim AT and Suite packages."

Given these independent sources, I propose the following neutral History section, worded to track only what those sources state:

== History ==

Discrete rate simulation was developed in the early 1990s at Simulation Dynamics, Inc. by Andrew Siprelle and colleagues.^[1]^[2] The methodology retains the discrete-event clock while moving flow through a system at rates that maintain mass balance; it was first published at the 1995 Winter Simulation Conference,^[3] and the term "discrete rate simulation" was established in the authors' subsequent work.^[4] The commercial ExtendSim vendor, Imagine That Inc., later described this "first generation" technology as "ground-breaking" and built a second-generation, linear-programming- based implementation upon it.^[2]
